Comments: I tried this stick for 6-8 hours of play, and compared to Ai98 it had too much power and less control!
This was not a stick for me.
From: Voya, 5/15
Comments: Excellent racquet. I've previously played the APD, Head Graphene Speed Pro and the Yonex Ezone Ai98.
This racquet is a nice blend of all those racquets. I've found the spin is equivalent to the APD, but with less power and more
maneuverability. It has less control than the Speed Pro, but more spin and more power. It has more spin and power than the Ai98
and I appreciated the additional forgiveness on mishits. For me, the balance/mix works and is what I was looking for. The
internal dampending technology is outstanding, which has enabled me to go without a separate dampner.
From: Kevin, 4/15
Comments: This is a super racquet on every shot. Strung with the Volkl Cyclone at 52 lbs, this is a superb racquet
with easy spin and is very arm friendly.
From: Rui, 3/15
Comments: Outstanding racquet! After playing for years with the Six One 95, I wanted a lighter racquet. I tried the
APD, PS 95 and few others, but all of them were nothing compared to the Ai 100. You can do everything with this racquet --
amazing balance of power and spin. Great on serve; maneuverable for returns, and it really surprised me on slice -- I didn't think
it would perform this well since it is on the lighter side. I added a few grams in the head and handle and now it is a beast. Im a 5.0
From: Dave, 3/15
Comments: I have been a VCore 100S user and fan which has been retired and bought a pair of VCore 100Si as the
recent iteration of vcore 100. Vcore100si is really great on shots made right at center but highly stiff, uncomfortable and hurting
for off center shots. As I read reviews, I decided to give the Ai100 a shot. One word, Ai100 equals comfort and a very nice,
forgiving feel on off center shots. Right now I switch between the 100Si and 100Ai. My experience is when switching to a stiffer
racquet, it takes some time to adjust to the right tension and your arm also adjusts. I will use the Ai100 as an alternate but stick
to Vcore Si because I rarely hit off center shots.
From: Obaid, 2/15
Comments: Was looking for a replacement for the EZone 100. It became too powerful for me as my game changed.
Demoed this and it was love at first sight! Very forgiving on the arm and a nice sweet spot. Good control as well. Strung it up
with Dunlop Black Widow 17g at 50 lbs.
From: Jackie, 1/15
Comments: I am trying to replace the APD 2013. Unless you take a full fast stroke, the balls are going out one foot
or so. Strung 4G at 54 lbs, Cyclone at 56 lbs. The Ai100 has less spin and more power in the sweet spot compared to APD.
Comfort is good. Played 4 times/9 hours -- maybe I need more time. I'm a 4.0 level with an eastern forehand.
From: Dean, 12/14
Comments: This is an excellent racquet from the baseline. I got more spin and power on my groundstrokes. It
didn't work as well for volleys (not enough touch) and serves (sluggish due to the balance and/or polarization). If you're a
baseline basher, definitely give this racquet a try.
From: Eric, 11/14
Comments: Great racquet. Switched to this from the Technifibre Tfight 320 as I needed something lighter, easier on
the arm, but still with good power. I'm a baseliner 4.0 player. Offers good power and control on serves and groundstrokes. Strung
with Yonex Tour Super 850 Pro at 52 lbs and close to perfect. Now tempted to try the Ai 98. Anyone tried both?
From: JK, 11/14
Comments: I was looking for a lighter racquet than my current one (weighing 12.2 ounces strung) and I think the
Yonex Ezone Ai 100 fits the bill. The racquet is maneuverable and yet very stable. There definitely is an adjustment period from
my earlier racquet which had a solid smooth swing. The EZONE Ai 100 was less responsive when strung at 55 lbs (Signum Pro
Tornado 16) but really came alive with 50 lbs (Babolat Hurricane Pro Tour 16). I found the feel of this racquet similar to Babolat
From: VM, 10/14
Comments: I enjoyed the solid feel -- as solid as I have ever experienced at this weight, and superb volleying this
racquet facilitates, along with a comfortably firm feel. Power sometimes seemed a bit too much and hard to control, but there
may be a learning curve here that I didn't allow sufficient time for. If you like racquets in the low 11 ounce range, this is definitely
one to demo.
From: Mike, 9/14
Comments: I like that it is easy to play like Babolat APD, Wilson Juice 100, etc. but this one is less harsh. Not an arm
killer like those. Easy to whip for that extra topspin, and very fast at the net. Big sweet spot. I'm still experimenting to find the
perfect string setup, but Black Widow 1.31 mm at 53 lbs is pretty nice. Like all Yonex racquets, this needs one or two extra layers
of overgrip on the buttcap to get it right. 4.5 level league player, heavy hitting topspin baseline player. Black Widow 16/Focus hex
1.10 mm at 53/52 lbs.
From: Mathias, 9/14
Comments: After demoing 12 racquets, I didn't love any of them. I watched the Tennis Warehouse racquet review
for this racquet and demoed one and fell in love! I got rid of my Babolat APD for this. I love the perfect balance of everything. Not
as stiff as a Babolat but still has power, great swing weight, awesome pop on my groundstrokes too! I am using Technifibre NRG2
and it feels plush since I have tendinitis. I am a fan of Yonex now!
From: Lee, 7/14
Comments: This raquet is quite simply the best all around 16x19 stick on the market. Topspin, slices, serves and
volleys are all solid. I have demoed the Prince Warrior, Pure Drive, PD Roddick, APD, Head Instict, Wilson Juice, Dunlop M4.0, and
Donnay Formula 100 (which was a close second). Not recommended for beginners but for 4.0 and above if the specs look like they
suit you go for it you will not be disappointed. I strung it with Cyclone at 54/52 lbs and am a 6.0 level all-courter.
From: Thomas, 5/14
Comments: After switching racquets numerous times over the past 2 years and not really finding the right one, my
search is finally over with the Ezone AI 100. I switched to Yonex last year, first playing the VCore 100S and then trying the Ezone
XI 100. I liked the Vcore 100s but I had trouble controlling the ball against heavy hitters especially at the net. The AI 100 is just a
tad heavier but it's enough to eliminate that problem. Not only can I control heavy balls much easier now but can also create very
decent pace and especially enormous spin. The first set I played I was sure so many balls were going out but somehow they all
spun into the court, also my opponents were sometimes beyond belief. There is not a single thing I dislike about it. The stability is
fantastic, control, spin and pace come very easily. I strung it with Signum Pro Tornado at 51 lbs, same as my other racquets. Long
story short, this is the best racquet I have ever played. I'm a singles player between 3.5 and 4.0 and hit with a lot of topspin and
extreme slice. Some of my slice balls spun so extremely sideways that my opponents couldn't even reach the ball, unreal.
From: David, 5/14
Comments: I am a current E-zone 100 user and love it. The Ai 100 is a different animal. I find the increase in swing
weight very obvious. This feels more like a baseline oriented racquet now versus an all court stick. I will stick to the old frame for
now and look elsewhere in the future.
From: Mark, 5/14
Comments: The best and most solid tennis racquet I have experienced in the past 25 years. The racquet has good
power but prioritizes control. Excellent in every way, I am very pleased with it. I do not consider a racquet for beginners because a
good whip is necessary to achieve good acceleration and spin.
From: Eduardo, 4/14
Comments: I have played with all of the EZONE line of racquets and Yonex somehow managed to make each version
better than the previous rendition. The Ai is simply put, a solid stick on all fronts. It is much better than the Xi on groundstrokes
without losing anything on the serve or the volley. It is a bit stiifer than previous versions but the lack of vibration makes it a
non-issue. A great frame for a wide range of players. Strung with Babalot VS touch gut mains/Babalot excel crosses at 58 lbs.
From: Tony, 4/14
Comments: Received the YONEX Ai 100. Overall impression: Very high quality construction and finish. Excellent
plow through rivaling my Babolat PD Roddick plus. Unlike the Babolat though, there are few, if any trade-offs. Comfort is quite
high, stability is excellent, great feel. Plenty of spin potential. The only downside was easily remedied: The stock grip is very thin
with no cushioning. I had that replaced for $5.99 and the racquet is great in all aspects. I strung it with Volkl 17 Gauge Psycho
hybrid, 54 lbs in the mains, 52 lbs in the crosses crosses.
From: Zivko, 3/14
Comments: Great racquet in the same class as the Warrior 100, Wilson Pro Open, Prince Warrior 100 or APD. Softer
feeling than it's 68 rating. Nice solid 330 swingweight. Plays nice out of the box. I swapped out the thin Yonex grip for a Wilson
Sublime and it added 5 grams. Lots of power but it's easily controllable with the right poly and tension Cyclone at 55 lbs is a
great starting point. Really does everything well -- groundies, serve, slice and touch and feel is great for a high stiffness racquet.
Headshape on the Ais is less square than in year's past and that's a welcome change IMO. If you like powerful 11-11.5 oz. semi-
players frames, you should give this one a try. It really has no downsides.
From: JackB1, 3/14
Comments: I have been deciding on which racquet that would suit my game between the Yonex AI 100 or Head
Prestige Graphene MP. The Head racquet is a very good solid control racquet but you have to generate your own power (Players
racquet). It hits very nice, good for the arm and shoulder, but it is a heavy racquet. So your reaction time will be a bit slow. The
Yonex AI 100 is a very powerful, light racquet, good for the arm and shoulder. It excels in all areas except slicing -- it is very
terrible when trying to execute a slice. However, since I play a lot of doubles, the Yonex fits my game style. Very good racquet for
From: Amett, 3/14
Comments: I've used Yonex for years. I am a bit of a racquet tester and have hit many of the new sticks that are
out. I think this one has something for everyone comfort, power, spin, and swingweight. Much better than the AeroPro Drive.
From: Andrew, 3/14
Comments: Big fan. I have been demoing several racquets since November. I tried the new Princes and liked them
(100 Tour, orange and yellow/98) and decided to step out of Prince and try Yonex for a while. Just really impressed with the
feel/weight of this racquet. Fits me well.
From: Rode, 2/14
Comments: I picked this up because I'm still looking for that 11.2 oz/5 pts headlight stick that I can say is perfect.
I take a big cut at the ball, big topspin. And I like Yonex sticks, but they haven't had many in this weight category that could be
considered a players racquet. Mine weighs 11.4 oz, added only an overgrip, and is 5 pts headlight. But the balance of this one
makes you feel it is lots lighter, and very fast. Which is good. Quickness is really apparent on returns where this is really good.
Serves also, while not the most spin I've had, it certainly feels controllable. Groundstrokes are very controllable but I'm still
looking for that string that will pull it back about a foot or so. Tourna Big Hitter Blue 17 at 53 lbs is just a little too big hittery.
Am going to try Weiss Cannon Black Edge at the same tension and hopefully that edge will grab a bit more and pull the ball down.
All in all very happy, my go to stick and I have lots of sticks.
From: Rob, 2/14
Comments: I've been hitting with Yonex raquects now for over a decade and this Ai version of the EZONE is
just recently switched to this version from the EZONE Xi 100 and couldn't be happier. I did add quite a bit of lead tape around the
frame to add more weight. The thinner beam in the throat allowed me to swing faster and therefor added more spin to my ground
strokes. I was more accurate with angle shots as well. Strung with Yonex Poly Tour strings. This stick gives me the confidence to
all out with my shots!
From: Carlo, 12/13
Comments: I put 5 grams of lead tape in the head and tried it, it's a real weapon! I tested all the 100s square inch
racquets on the market, but this stick beats them all. It's very easy to use, extremly powerful but also very controllable due to the
enormous spin. This stick reminds me of a blend of a Pure Drive (power) and an AeroPro Drive (spin), but with much more touch.
Also, it is very comfortable on your arm -- I can't find any mistakes! I strung it with Solinco Tour bite at 24/23 kilos.
