Wrecked my arm from using it for 4 months. Ulnar side of wrist and medial epicondyle. I took a month off of tennis. Don't buy it. Never had arm problems before.
Its the mix of high swingweight and not head light enough that was a fail for me. If it was 7-8 HL strung it would be great. If you want a heavier Yonex go with the VCP 330 it feels much more plush at impact then the EZT and more headlight so it doesn’t feel sluggish

Really interesting, I too never had tennis elbow in my life after 35 years. I loved playing with the EZT but the tennis elbow has knocked me out for about 2 months.

Just interesting. Tennis elbow develops when you grip the racquet with excessive force. It often happens when a player is out of positiion (slow preparation), trying to make the shot, hitting with a stiff racquet (a large sweet spot). The player swings at it (all arming), using additional forearm and wrist action to make the shot. Most are off-centre hits (though the sweet spot being large), making the player compensate by gripping tighter. Stiff racquet, stiff strings (eg. stiff poly) and high tension aggravate the damages.

Even pro players get short-term discomfort when they execute a tough get or save (which may be off-centre), trying to save a point. Yet that does not happen often and gear set-up and anticipation can mitigate the discomfort.

Similarly, in a doubles match, when a hard hitter with a rocket launcher (eg. Pure Drive) once in a while hits a fast and heavy shot to you (the net player), this probably will draw an off-centre hit or forced error from you. No matter how good you are, your wrist/forearm hurts. :)

This will take some time to heal. Or if you have a fast mind, let go of the ball. :laughing:

I have exactly the same issue with the new ezone 98. I developed hand / arm issue after using it for a month. I have never had any tennis related issue before. I had to leave tennis since last October and my hand is still not healed.
Yonex ditched the proven AI and dr 98 and They screwed up the formula again ! Wth.

I see people are coming onto the “you don have the right technique”. Let me ask you this. Why didn’t I have any issue with my Ai98 and Dr 98 ? I still have them and will continue to use them this coming season to save my hand/ arm.
Something is really wrong with the 2020 line. Wth yonex. Why? I really wanted to like the new ezone.

I agree, I think it's presumptuous to say people having arm issues have bad technique. I think it's the opposite as most folks playing with this racket have good techniques and can swing a heavy racket. It's possible that it affects some people and not others. In my case I have played for almost 15 years without any TE issues from walmart rackets to prostaff, puredrive, aeropro, head radical, gravity pro before this. No issues except shoulder from babolat.
Also have switched to VCore98(new one) and am not experiencing any of the issues with that either.

Interested in hearing from people’s experiences with this frame. I have had a few acquaintances that have bought this racquet and now don’t use it because it chewed their arm up. Also Jonas from Tennis Nerd has commented on this as well. Like to hear your views, good and bad and why you think people may have a problem with this frame.
One thing to understand about Yonex racquets... because of the hoop geometry, with the tip squared off... they effectively play longer. The wider hoop shape of the E Zone tour compounds this effect of shifting the sweet spot higher.

With an impact point shifted more than 1/4” higher up relative to the tip, the effective mass at the impact point is much lower compared to conventional oval racquets of the same swingweight and frame length.

The lower effective mass means the shock transmitted to your wrist and elbow at impact is higher than you would expect. Essentially, a Yonex plays like a 1/4 extended frame, with the same pros and cons of an extended frame.

To be clear I was not trying to say that bad technique is the issue here (although that certainly can be a factor in some cases) what I am saying that it's hard to switch racquets and keep the same technique and that is in my opinion 99 percent of the issue. This is amplified with age so older you get harder your arm will be able to adjust to these equipment changes in sw weight balance etc...

So to me that is saying that at this point of your tennis career your arm your technique whatever prefers lower swingweight but firmer more powerful racquet. Perhaps you are used to that. I get it because I find that ezone is not as powerful as vcore and that flex in the throat can really bother some. I bet that you would like ezone 100

You maybe right, though Gravity Pro's swingweight is similar and I don't have any issues with that racket(much lower RA though). My daughter does play with the EZone 100 and I've tried playing with it. My arm isn't fully healed so I was a little cautious and didn't swing out. I will give it a shot again in the summer hopefully once the arm is fully healed. I do like the VCore98 2021 though, it has a lot of power and more spin than the EZ. I'm planning to add some weight to see if i can get that plough through I miss from the EZT.

holy Molly...I thought it was just me with the EZT. Had it for about 4 months and love playing with it. Luv it even more than my EZDR but in early Feb I started feeling it on my forearm and still recovering. I'm not sure if its tennis elbow or not since I don't feel the pain in my elbow more on the forearm. Not sure what to do with these frames, I thought it was just me trying different techniques or playing too much but now I'm hearing TennisNerd and Karue were having issues and now this thread.

Anyone wanna buy my EZT? :p got 2 1/4s and 1 3/8s...

I own 3 EZone Tour's and all with either Cyclone or Hyper G and I have no arm problems. But I use kinetic chain groundstrokes and I don't muscle or arm the ball. I don't know who said it above, but he brought up a good point that this is not a Pure Drive in which you just arm it and use improper mechanics. It may look like a PD from a distance but it certainly does not play like one. The only Babolat that I could compare this to is the Pure Aero VS. But If you have arm problems with this I have to place blame on a combination of mechanics and poly strings.

Put it simply. If you play with a gear set-up (racquet + string + string tension) and you feel it is wrecking your arm, stop playing with it immediately. Try some other gear set-up. Switch to arm-friendly racquets (there are a lot out there). With strings, fall back on multi-filament or synthetic gut. I think most recreational players are better off using them. I play with full bed poly (middle of the road in terms of stiffness) @ 48lbs. I cut out the poly when it drops in playability (so not a chance to beat up my arm against firm wires).

Quote some user feedbacks on EZT on TW. One has no arm issue. The other has :

Comments: Compared to my older DR 98+, I found I like the plow through, and opponents have said my ball seems heavier. It for sure requires a long hitting zone once you get the racquet moving. You won't want this to hit Jack Sock's forehand. I strung with Yonex Poly Tour Pro at 48 pounds and haven't experienced any harshness as others have said. I also tried the current EZONE 98+, it's fine but I like the plow better than the length, and the EZONE 100+ is too stiff and harder to control. I'm a 4.5 level player who likes to serve and volley, chip and charge.
From: Phil, 3/5/21

Comments: This is a great racquet but strangely enough it is very harsh and stiff. I used to play with the RF97 with a stiffness rating of RA 68, which did not feel as stiff as this supposedly RA 62. It's either incorrect specifications or Yonex messed up. I do not recommend for those with sore arm and wrist. Definitely not a racquet for guys who use lots of wrist or have a small take back

I have 2 EZT’s. Have both of them with a leather grip and lead tape from 10 to 2 across the top. Strung @ 40pds with Hyper G 17g. I had some issues with feedback and put an “O” dampener. It seems to help with all the extra weight and dampener. When I first tried it in stock form my elbow felt pain. Honestly I felt it was due to it swinging so fast that I had trouble decelerating after contact. When I added the weight I was able to swing and the added weight slowed it down after the finish. After that I was able to take a full swing and not feel elbow pain. I also had the same experience with the old XI98, but I like the swingweight of the EZT. Have thought about trying the Vcore 98 but I really like the weight of the Tour. I also am waiting for the plus version Vcore 98 to come out.

"But I use kinetic chain groundstrokes and I don't muscle or arm the ball."

A good point :)
I call that modern strokes.

You probably nailed it. Great analysis

Read a bit on Isometric and Isometric Expansion (and pic illustration) (above link). Not sure about shifting the sweet spot higher. If true, it should be applicable to every Yonex racquet with Isometric shape.

Ezone 2020 has a slightly wider hoop (3 and 9 o’clock positions), thus has a wider sweet spot, according to Yonex's theory.

If a player's play style frequently relies on and takes advantage of a larger and wider sweet spot, the probability of getting unwanted consequences is higher (same as using a large sweet spot tweener). I would say.

Interesting to see the description above by Yonex :
"For advanced players looking to dominate with more power and comfort"

Yonex does not lie ... if you use it correctly.
