Comments: Excellent softer poly with nice power. I enjoy it both in a full bed or as a cross with natural gut mains.
From: Greg, 3/15
Comments: Great string! Very comfortable with excellent power for a poly. The strings are also slippery and provide
great access to spin.
From: Ry, 7/14
Comments: I used these string for quite a while and they held up great, in fact they lasted longer than any other
poly I've tried, which is great considering they're pretty soft and comfy. But, they are just too expensive for long term use, I have
since gone to a generic brand of similar strings for $25 per reel. When will Kirschy realize their strings are not so popular in most
countries and start dropping the price accordingly? I'd like to tell others about them but have gone off them due to the price.
From: Michelle, 7/14
Comments: The first time I used these strings was in my 2011 Pure Drive and I was amazed about how much my
game improved. Striking balls was easier and the strings offered a great balance of power, control, and spin while still maintaining
tension well. I use these now in my AeroPro Drive and still love to use these strings!
From: Andrew, 5/14
Comments: This is my new go to. I've tried dozens of polys. All the standards RPM, 4G, TCS, ALU Power rough, Tour
bite, Signum Pro, and many more. This string is soft but not mushy but has enough crispness to feel like your really hitting the
ball. It has great control and better spin potential than many of the shaped polys out there. The ball seems to come off the string
bed the same way every time which translates directly into confidence in my swing. I've already converted to it and made a couple
more believers out of people on my teams and at the club. Great string. Highly recommended.
From: Dallas, 4/14
Comments: This is still one of the best polys on the market! Nice soft string, with excellent power for a poly.
From: Anon, 8/13
Comments: This string has tons of power and spin. It's a softer polyester as well so you can safely string this
between 55-60lbs. It's not very forgiving the first hour that you play with it, but after the strings break themselves in and settle
down, they pocket the ball really well.
From: Patrick, 9/12
Comments: I have this as cross stings at 48 lbs with 17g RPM Blast on the mains at
50 lbs on my Head YOUTEK IG Prestige Mid. I like them a lot, and have little to no aggravation to my elbow tendonitis.
From: Anon, 8/12
Comments: I am revisiting this string. I had bought a reel of it (17 gauge) and tried it out on
3 frames: Prokennex ki5 16x20, Head YOUTEK IG Speed 16x19, and Head MicroGEL Extreme
Pro. Now I am trying it on my current frame, the Wilson BLX Pro Open 16x19. I like it so far. It generates tons of power,
sometimes too much. I strung it at 58 lbs but I guess if you use a frame
like the one Nadal uses then I think you would go up a bit in tension. Spin wise, it does a
great job. I have another frame with Sigmum Pro Poly Plasma (orange) 18 gauge. Both
strings are awesome but I think Poly Plasma has the edge by a fraction.
From: Gino, 8/12
Comments: Kirschbaum makes great polys and Pro-Line II is probably the best soft poly
on the market. Nice pop, spin and feel are attributes of this string. If you like softer
polys give this one a try.
From: Anon, 6/12
Comments: Great string the only problem is when you need forty feet for a large racket you sometimes
get thirty nine feet and come up short. Poor quality control on Kirschbaum's part for string length. They should always
make sure you get 6 inches more than forty feet!
From: Tom, USA, 1/12
Comments: I put this string (full job) with the same gauge on my frames (Wilson Pro Open) at 54 lbs and
could not control the ball because of excess power. It felt that I had strung at below 50! Not sure if the weather
contributed to it though. I had tried to hybrid (used Gosen OG Micro 17) before and it feels nice. I felt I had more
control. I just bought Gamma Professional 17 to use as my cross string and will go up in tension say 57.
From: Gino, 12/11
Comments: I have used this string as a full bed for a whole year now. I played with a Yonex RQiS Tour.
What I found interesting was that even though (definitely the racquet) both the racquet and string had very low power
ratings, I had more than enough power. Spin was moderate. feel was good, control wasn't great. durability was
amazing, and i mean amazing. I hit with generous power and spin and the durability of the string lasts months, even
with hitting 4 times a week. I have been completely satisfied with this string through and through I am changing just
out of curiosity to see what different strings offer.
From: Brandon, 11/11
Comments: I play with the Wilson BLX Blade 98 and I've been experimenting with different string set-
ups(MSV Focus HEX 1.25, Tecnifibre X-One Biphase 1.24) for a while. I came to a conclusion that this string at
24/23kg suits my needs the best as the racquet frame is rather stiff(64). The string is very soft and light-weight unlike
most polys on the market and offers
unmatchable pocketing along with great touch/feel and control. It doesn't offer that much power and the spin potential
is low, however for me it's the best string so far. Definitely worth a try guys!
From: Younes, 10/11
Comments: I'm an avid Kirschbaum user. Tried this string and love it. Nice ball
pocketing, lots of spin, not too much power, but you get control in
exchange. Came back this time to buy a reel. Sadly though the price went
from up. Will put this deal on hold...
From: GC. 10/11
Comments: In regards to Gino's comment, I also have the Gosen Micro Sheep 17 (Natural) and currently
hybrid it with MSV Hex Focus 16 and it's great on my Rebel 95. I did try it FULL bed on Babolat AeroPro Drive. And it is
amazing, lots of pop, spin and very good net clearance but penetrating shots.
From: Alex, NTRP 4.0. 6/11
Comments: I used this string in the mains and Gosen Micro Sheep 17 in the crosses.
I play with a Head Isospeed 16x19. I am not impressed with this string.
It did not fit my playing style. I lowered tension in the mains and crosses to 50lbs
expecting to gain some power. I didn't get what I expected. That doesn't
mean the string is no good. Simply, the marriage didn't happen between
player and string with this new stick. I am curious though to try this
string (full job) on one of my Microgel Extreme Pros I have in the trunk of my car.
From: Gino, Long Beach, CA, USA. 4/11
Comments: Good cross string. I used ALU Power in the mains but needed to find a good cross string to
soften the string bed just a little bit, and this might be the one. This is a soft poly string, just a little bit softer than
traditional poly string. It plays as much as 95% the same as Topspin Cyber Blue, and this string has more oil on it. It has
good control, comfort, medium power level and good feel when combined with the ALU Power. (Head Youtek Prestige
MP, Main: ALU Power @ 59 lbs, Cross: Pro Line II @ 58lbs)
From: Jack, Denver, CO, USA. 4/11
Comments: I use this string on my kblade 98 (18x20), 52x50 lb, very special feel, good for hitting hard,
spin, power, control, touch, everything. After an hour or so you seems like the tension drops a bit and then stabilizes.
Good durability as well. I have one of the racquets strung with Luxilon alu power at 50x48 lb - and this one gives me
some discomfort in the shoulder and elbow area. Compared to the lux, the proline2 is more common sense - you have
to work hard with the Luxilon when the kirsch delivers without the hassle (and the discomfort). It is lighter too - a good
few grams than the Luxilon.
From: Nick, Canada, 12/10
Comments: Strung at 62lbs on a Wilson K Factor KSix-One Team. Groundstrokes just as good as Luxilon
Big Banger (possibly better), however you have to work the slice more with your arm. Overall nice feel, control and
From: Tai, Melbourne, Vic, Aus. 6/10
Comments: Good string, however, it is too soft for me and it has no power at all. If you don't put a
dampener on this string will drive you crazy!
From: Adam, Hartford, CT, USA. 3/10
Comments: This is the best string. Both me and my mom love this string. We tried others, like Zo Sweet,
but this is the best. At first we hated the red colour, but I have grown to love it. She still hates it but sacrifices looks for
performance. Best string. Will never use another.
From: Lulu Riley, Hamilton, NY, USA. 12/09
Comments: Used as main at 53lbs on AeroStorm with PSGO16 in cross at 58 lbs. Played very stiff for the
first couple of hours. I have not had arm problems in a while but this string gave me arm and shoulder pain. It seemed
to play a lot better after two hours probably due to a little loss of tension. The string bed still felt very firm after 4
hours of play. The control is good, spin production is pretty good and decent power. Not much in the way of feel or ball
pocketing at this tension but volleys were very crisp and solid. I will try it again at lower tension and with perhaps a
softer cross string. So far I'm neutral on the string over all. I'm looking for something with more feel. This string
reminds me of Luxilon Alu Power but looks better in red, which is why I bought it.
From: Lance 4.0, New York, NY, USA. 9/09
Comments: I have been looking for a replacement for my Alu Power crosses(with NXT mains)for my arm
and I have finally got around to trying the Pro Line II after reading about how good it was.
Well I could not believe how this string played - all the great things people had said about it and after the first hour of
play I was utterly disappointed by the way it played.
It was dull, boring, out of control - almost the opposite of what I was used to. Price is very good but you get what you
pay for.. I like value and I felt like I was getting what I paid for, but there was no reel satisfaction. Before you get a reel
of this stuff, consider a reel of Lux while it is on special, will be well worth it.

Comments: What the other people say is TRUE. This is the Best Poly out there. I have my Prestige strung
with a full bed of Pro Line II and my game is better than ever. I agree, this string is magic. Bye bye Big Banger.
From: Palmer, Huntsville, AL USA 09/09
Comments: Best Co-Poly on the market. I have tried them all and ProLine II kills the rest. As for tension
maintenance, the guy below me did not have his racquet strung properly. For a high quality co-poly the tension
maintenance is fantastic. Serious players will never have their racquets strung for more than 4 weeks with the same set.
This string is absolute magic!
From: Terry, Greensboro, NC, USA. 09/09
Comments: Got these strings because I went to a professional tennis shop near my house and the guy
stringing the racquets asked why I wanted to put Big Banger Rough in my strings because it is bad for the arm and is
out dated technology... He didn't force it on me it was my choice.. and I am glad I chose the string because I can feel
how much grab the strings have on the ball. I used to use a N Blade 98 with 18x20 string pattern with NXT strung at
50lbs and got no pop or spin on the ball especially on serves... now I have a Ksixone 95 16x18 and with these strung at
53lbs and can kill the serve and get that awesome spin I have been missing for awhile now. If you are thinking between
this and ALU Rough, go this - newer technology/cheaper/better on arm.
From: Alex S., Plantation, Florida, U.S. 7/09
Comments: NO MORE BIG BANGER! This string has the same benefits as alu string....except it is easy on
the arm and has a soft touch. It may lack just a bit on the control side....but when weighing all the benefits...feel,
control, power, PRICE.... this string wins out with me. I play this string in the Wilson k 6.1 as my mains...Wilson Nxt
From: Stephen, 4.5, Willow Springs, MO. 2/09
Comments: The best string I ever used! Easily beats Luxilon ALU Power in terms of feel, control, power,
durability, tension hold, and value. Best of all it's much softer and easier on the arm and wrist.
From: Anon. 1/09
Comments:After many years, I had pretty much given up on finding a polyester string that offered both
feel and kindness to my longtime, tender playing arm. This string has successfully addressed all of these issues, along
with offering some extra pop and spin. I read some reviews that suggested that it doesn't even need to be used in a
hybrid setup, so I tried both ways. It does play great when put in both mains and crosses, though I have gone to the
17L for maximum feel. Durability is good, too. Thanks, Kirschbaum!!

Comments: I'm absolutely DUMBFOUNDED right now! I had my new Head MicroGEL Radical Mid+ strung
with these strings PURELY because of all the positive comments about them, and everyone is ABSOLUTELY correct--
these strings are WORLDS better than Pro Hurricane Tour, Big Banger Rough, and K Gut Pro COMBINED!!! They feel soft
and firm at the same time, with HUGE spin potential. The thing that frustrated me with the Pro Hurricane Tour & Big
Banger Rough is when you strung the entire frame with it, you had control and spin, but the frame felt DEAD and
KILLED my arm. I've played with these strings for over 10 hours now on my dense 18x20 string pattern frame at 55lbs
and it's the BEST combination of control, spin, and "gentle" stiffness I've ever felt. I think this is the last stringing setup
I'll ever use again. It's perfect. Try it out for yourself, and don't bother with hybrid use in my opinion. The feeling is
amazing with it in the whole string bed. This was my first try using Kirschbaum strings, and I'm SO glad I did!!!
From: Jared, Moscow, ID, USA, 09/08
Comments: This string is soft and has some nice power, but it has no control whatsoever. Next time I
get my racquet strung it's going to be with Babolat Pro Hurricane Tour 17g.
From: Anon. 6/08
Comments: Finally a soft poly that holds tension well and has lots of power. I use it in a hybrid with
Gosen Micro Sheep as the crosses. The fairly stiff characteristics of the GMS complement the Pro Line II. I don't like
mushy crosses as there's less spin. The Pro Line II has a much nicer feel than the Luxilon Big Banger, since the Big
Banger has to be strung at a much higher tension. With the Pro Line II, I've never had any arm problems, with the Big
Banger I have problems within minutes. I string the Pro Line II at 51.5 pounds, and the other crosses at 54. It feels like
a synthetic gut at 59 pounds. o string movement and plenty of pop. Works well on my Wilson nCode nSurge and
Dunlop 500 Tour racquets. Would be nice to have a mini-reel since the 149 reel is too much. Besides once you string
your racquet like I did, it will last for months and months. I've been cutting out my strings every other week until I
found this combination. Nothing else comes close, and trust me, I've been through just about everything out there.
From: David, Jupiter, FL, USA. 6/08
Comments: This is the best poly out on the market by far. I've compared this string to other poly's like
Pacific Force 17 (lost it's tension to fast) and Tospin Cyber power 17 (elbow soreness). Pro Line II has excellent bite to
all shots. I had no problem with my backhand slice, flat forehand, heavy topspin forehand, and over the top one
handed backhand. I found this string to be very comfortable for my arm and offered great control to all my shots. I
strung my Yonex RDS 500 at 52 lbs. full set no hybrids. I'd definitely recommend this string to all who like poly's and
don't waste it by splitting it.
From: Anon, Chula, CA, USA, 05/08
Comments: I've tried many polyester strings brands, but this one is an absolutely amazing poly. I sting
hybrid - Gamma Live Wire XP and Kirschbaum Pro Line 1.25. The best combo I ever have. Kirschbaum and WeissCannon
is the best poly on the market today in every way!
From: Honza, MD, USA. 5/08
Comments: This is one of the best polyester strings I ever played with, great control, spin, speed and
comfort. The only negative thing about this strings: If you play with heavy topspin, it will begin to move around after 4-
6 hours. That's why I am gonna use it as a cross string in the future.
From: Kristian, Oslo, Norway. 5/08
Comments: This string has everything. You get great power, control and spin, and the durability is great.
The strings outlasted my racket (my racket cracked when I served the ball). From all 8 hours I got out of this string I got
an extremely consistent response from this string and they never moved no matter how much spin I put on the ball.
From: Ben, Cleveland, TN, USA. 3/08
Comments: Love this string, best poly ever, not the most powerful but has the best feel and control. I
hybrid with RIP Control as a cross and it's just sublime. Try it, you won't be sorry.
From: Chris, Walnut Creek, CA, USA, 02/08
Comments: I've tried many polyester strings and Pro Line II is really the finest offering around - it is as
comfortable and resilient as poly gets and also is incredibly durable! I hit big and break a lot of strings generally but
have simply been unable to break these in my stiff, open string pattern frame! String only 1-2 lbs lower then synthetic
From: Anton, New York City, NY, USA, 02/08
Comments: Exceptional performance and value. The best polyester string that I have tried. Great for
tension maintenance, very easy on the arm, great for producing some vicious spin, and excellent compromise between
power and control.
Serving is a pleasure with this. The 3 pack price is great too. If you try just one polyester string, try this one.
From: SK, Mission Viejo, CA, USA. 10/07
Comments: Oh, PERFECTION! I'm used to companies letting me down with their promises, but these
strings don't lie. Everything you are promised is delivered. My strings feel as tense as the day I strung them, and the
bed itself doesn't move. While the strings are as soft as a pillow, they nonetheless deliver excellent power and control
over the ball. I'm currently using these together with my HEAD FXP Prestige. Perfect match, if you ask me.
From: Anon. 7/07
Comments: Strung my aeropro drive with the kirschbaum pro line II 17 and all I can say is that this string
ranks up there with the best out there. There is no string movement and I strung it at 54lbs. There is plenty of power,
spin and control. This will be my string of choice from now on. The tension after 6hours has not changed from when I
first hit with it. Amazing string. Worth a test drive.
From: Bob, Toronto, Ontario, Canada, 07/07
Comments:I have always loved Kirschbaum strings and this is no disappointment. My favorite string so
far, it has great access to power and spin, with a satisfying feeling every time I hit the ball. Been playing with it for
about 6-8 hours in the past week and it is still going strong, very little string movement. Just make sure you have no
problems playing with a red string, I guess it is an interesting change of aesthetics for me. 5.0 all-courter with heavy
From: Bill, USA, 07/07
Comments: Absolutely amazing! The feel of this string is unmatched. It has extreme control and power,
while still managing to feel soft as a feather. The tension seems never to fail, and the strings just always seem... new.
Plus, it's helped me in my quest to become the reddest tennis player ever. I already had the red shirt, red racquet
(HEAD Flexpoint Prestige), red bag, red hair and face, and red shoelaces. After all, red is statistically the most
intimidating color... right?
