Comments: A big thanks to TW for the customer feedback section and all who recommended to try this string. Nice
comfort, great control, perfectly low powered for my game which allows for aggressive cuts and lots of spin. Great for baseline
hard hitters with surprisingly good touch at the net too. Proving to be very durable with long playability. Have tried a lots of
strings in the last year and these are in my opinion, very good, regardless of the great price. Waxy and very stretchy for a poly --
takes a long time to completely stop on my drop weight machine but strings up easily otherwise. Will buy another reel for sure.
Comments: Not a bad string. It is very soft and I think it plays great when the string is fresh. The only downside is
that this string is only good for a hitting session or two.
Comments: Overall, this is a great string. Just switched over from RPM
team 17, which was 16 bucks a set, and this string feels identical, and
it's only half the price. The only reason I bought this string was to
put it in my high school teammates racquets, and I had run out of rpm.
So I tried it for myself, and it was the best decision I have ever
made. So great for the price, and I recommend it 1000% I usually break
string about every 2 weeks, and the setup I have now is now running on
3.5. I can't say anything bad about this string at all!
Comments: This is a hiding treasure. It is a soft and durable poly. I hit with heavy topspin and most
polys last me about 5 hours. ISOSPEED has lasted over 10 hours and still counting.
Comments: String is awesome and plays just like brand name string!!! I play college tennis and I am
always looking for the perfect string. I have now found it! I figure the best way to choose a string is by comparing the
Pros and Cons, so here goes: Pros- 1) Very soft on the arm
for a polyester. 2) Great ball feel. 3) Great ball pocketing which generates amazing spin. 3) Groundies, volleys, and
serve are very crisp. String offers great control. 4) Very cheap in price. 5) Popular black color that everyone seems to
love now a days. (Thank you Nadal). Now for
the Cons- 1) String dies out after about 4 hours of hitting and loses its feel. But at $40 dollars a reel.... who cares!! This
is my new string and I don't plan on changing anytime soon. The Pros totally outweigh the Cons. Try the string for
Comments: This string is great. Nice topspin and power (strung at 54-55 lbs) on Babolat AeroPro Drive
(old version). I have tried a lot of strings out there, and this one is great, plus it does not hurt my arm or my brother's
arm. And for the price it is a deal. Although I may have noted some tension loss it does not really matter. I have been
using it for about a week now without breakage. I'm not quite sure if it is as good as the Babolat Hurricane Tour, but I
will compare it when the black ones break.
Comments: A softer and very playable polyester at this price point? I've played with many polyesters
from cheap to expensive and compared to many, the playability is comparable. Don't get hung up on brand names, just
buy it. It's worth the risk and easy on the arm.
I play at the 5.0 level and will stick with this string. Farewell to over-priced polyesters. I'll buy another stick with what I
save on strings.
Comments: Good string for the price. I do customize and also restring racquets for the 3.5-5.5 players
who look-up to me because of the level I play. Many of them just want poly because nowadays is the polyester era, so
they want experiment and find out about poly and co-poly playability and feel and some are also low NTRP but string
breakers. So I also have reels of Gosen mono polylon 17 /1.24mm, which is great buy.
The ISO string is good choice for the $ but don't ever think that ISOspeed baseline is good quality Co-Poly composition
string for the price. It's just basic monofilament string with attractive black color.
This string is in different league than the rivals like Tecnifibre BC, Luxilon BB, Signum PP, and WeissCannon. So please
do not buy this string if you thing it will play with same tension maintenance like the RIVALS!!!
Comments: Not bad for the price string but absolutely no comparison with a Luxilon or a Babolat
hurricane tour. Absolutely not the same quality. If you looking for a cheap string this one is good as many other brands
at the same price range but if you looking for a performance string buy a Luxilon or Babolat hurricane tour. Signum PPP
is better but stiffer, Cyberflash is also better.
I've tried many different full poly setups, and this one is as good as any, better than most. A little livelier than
Cyberflash, not as "trampoline" like as Signum PPP or Head Sonic Pro. Better on the arm than most, too, although I don't
have much of a problem with that anyhow. I string it at middle tension (57) in a Head Youtek Radical Pro, and get tons
of power, plenty of pocketing (creating spin), and great control as well. Don't be fooled by the price tag...great string!
4.5 all court, singles and doubles. Play 3-4 times/week.
Comments: This string is made in Austria. Put this string side by side to the HEAD Sonic Pro...it's exactly
the same thing. I guess it's even from same factory, same base material, same packaging, same knot tied on the end of
the reel. ONLY diff is label. Cheaper than Head Sonic Pro. Shouldn't be too bad. I live by restringing racquet. It looks the
same to me to sonic pro. Buy it for cheaper price as the reason. Have fun.
Comments: Great string! I am a solid 3.5 all court player and I have been using this string since the
beginning of the summer and have it in all of my setups. Great control from the baseline and has great pop. I have
increased control on both sides and am more confident to go for high-risk shots. The string increased my spin
generation; my racquets are 16x18, so spin potential became much greater. After about 15 hours of use, string seems
to lose tension, which isn't all bad. I have tried to hybrid with multi and the multis didn't last extremely long (the
baseline string cut right through it within a few hours). I can go all poly and doesn't hurt my elbow, which is great.
Definitely recommend. Will try the others in the baseline series.
Comments: What a bargain! For the level of feel, spin and power I generate with this string I should be
paying premium price. I was hesitant to purchase a reel without trying it, but it's just like purchasing 2 sets of my old
strings (ALU POWER) so what the heck, might as well try it. Man was I in for a surprise. I feel like a fool buying ALU all
those years. This string even feels better on my arm. If this is how ISOSPEED's cheap poly feels I wonder how their
premium line performs. My advice to you guys, definitely do not hesitate to buy this... thank me later!
Comments: So I just lost in the final in a sectional junior tournament, using my Wilson Enduro Pro string
on my Babolat Pure Storms. Before the final, I strung all four of my racquets fresh with Enduro Pro. All my strings were
dead on all four racquets before the end of the first set (This was an intense final). I couldn't generate any spin, so I
ended up losing pretty badly after that. I had ordered this Iso-Speed string like a week before the tournament. It never
came because the passes were closed in my state (WA) due to flooding. So today, I finally got my Baseline Speed string,
and used it in a several hour session with my coach. They still feel fresh. Superb tension maintenance. The feel is
great-- no arm damage, even with the all-poly combo. Spin is better than with any other poly I've used. Great control,
and tons of pop. This string is probably the only reason I'm alive right now.
Comments: WOW! Spin feels like it is at the top of your fingers. You can get so much gyration on your
shot and the durability of the string is definitely worth the price. It's the bomb! Every shot explodes off your racquet
and hits the ground spinning hard. This string is also good with moonball shots. Anyone who wishes to play like Nadal
should purchase this string. I use it in local tournaments and it delivers!
