New Ezone racket

Just got to do a very limited hitting session with the DR's. Initial reaction is that the 98 plays very similar to my AI. Feel is very similar and there is a really good level of control. I was pleasantly surprised by the 100 and after never trying the AI version, I was curious to see how a lighter, less stable frame would feel. I thought the 100 was very easy to wield and it gave me a lot of easy power, albeit a sacrifice in control. These demos were strung with 2 poor setup's so I am going to re-string them with a poly and see how it goes. The 100, if I were to switch to it, almost 100% needs lead to both stabilize it and make it more solid feeling.

Yes both unstrung. I went into a tennis shop and compared the AI to 8 different DR. They are all a little under 1/4 in longer (ruler only had 1/8 gradations). The weights were all 10.91 to 10.95 oz, and all 10 headlight, with swingweight from 285 to 290. So, quality control is very tight but the new mold 2The AI was same weight, but interestingly swingweight was 293, which is really confusing to me it is shorter and feels much quicker to whip around.

Oh, I see, so you were demoing the 285g versions of these racquets? How did you like them? Did they offer enough comfort and control?

No these are the 310gm versions, the standard DR 98. Those 285-290 numbers are the swingweight of the UNSTRUNG frames, which they tested for me on the RDC innthe store. I cut the strings from my AI to have to compared, so the 293 sw is unstrung. When you add strigs it adds approx 30-35 points to swingweight

I love the feel on impact of the DR versions, it really is more crisp and stable and has more zing to it, but to me it swings really different than the AI. I was going to switch to the AI then the DR came out and TW thought it was the greatest thing since sliced bread, so I'm really trying to make it work for me, hence the investigation into the specs. I think it's the extra length that is throwing me off

I've now tried both the DR 100 300 gram and 285 gram (coming from AI 100 LITE leaded up to 292grams) and i don't like either of the new frames. I can't exactly pin point why but I think the new grommet hole shapes (rectangular vs circular of AI) is making it more plush and less control for me. I'll give a couple more hits with the DR then if i don't like it I will stock up on the AI 100 Lite
 
Although I haven't played with the ai series much at all, I have had the DR 100 for almost a week now and it is a very solid frame but I do feel I have to work a bit harder than my 2013 APD. It's definitely not as whippy and I can't be lazy on my shoulder turns or else I will be caught late. Maybe this will make me a more solid player. Or not....

Sorry meant to say the quality is very consistent, but I think the new DR mold is just longer than the ai one

Small difference in length may be caused by different butt cap (Yonex EZONE DR comes with SONY Smart Tennis Sensor ready butt cap). The graphite frame should be identical in shape, width and length.

If I threw 4 grams of lead in the butt cap what is the balance going to be like on the 100? 5 or 6 HL? Does anyone know what the strung weight plus damp plus over grip is on the frame?

I got my first ever Yonex today which is a DR98 that I ordered based on all the raving reviews. I was hoping that this model would fill the void between my Head pro stock Prestiges (TGT393.1) and my the couple of Pure Aero's I bought because they are easier on my sore wrist and that I happen to play really well with but tend give me soreness above my elbow when I serve a lot. My Yonex is 325g strung with a bp of 31.8 and a SW of 318. Lovely feel but I lost depth and power compared to my other racquets. Probably need to lead it up to a SW of 328+ to give it a fair chance.

I switched out the buttcap for a standard one, and you were right, now the rackets are identical! still have to get it restrung, but will report back my findings. thanks for the tip

hey guys! I've got a question for those who have both the Ai98 and Dr98. Do you guys feel that there is any vast differences between the two sticks? or am I right to say the DR is just a more stable version of the AI?

Tried my DR100s for around 5 hours now, and honestly I can't tell any difference between the new ones and my old AI100 bats. Maybe if I didn't string them so tightly I'd be able to feel a difference, but as it is I think I have paid £140 per racquet for an updated paint job. Not that I am complaining, as regardless of whether it says AI100 or DR100 on it, it is still a top notch racquet.

I just wish manufacturers would be a bit more honest. Just say you have updated the aesthetics and cut down on all the bull**** marketing of the supposedly game changing new "technology".

It's basically the same racket but the main difference is the feel. It's a bit like the black/silver Blades v the black/green Blades. The Ai98/100s were quite muted, soft feeling frames. The DR98/100s are still comfortable but there's more feedback (and also vibration coming through the racket). If I were to stick my neck out (I've tried 5 x Ai98s, 1 x DR100 and 2 x DR98s), I'd say the DRs feel more polarized to me but it could just be manufacturing variation.

I received my new Yonex EZONE DR 98 (310g) yesterday from Tennis Warehouse Europe - I decided to buy from TWE as the exchange rate meant that it was at least £20 cheaper than buying from a UK retailer.
The colour is slightly more lime green than I expect, although it does depend somewhat on the light you at at it under. I'm tempted to buy some lime green overgrips instead now as from looking at images of pros using the frame/paintjob and retail images I thought it was more yellow.
I've had it strung with a full bed of Luxilon ALU Power Rough.
I won't be able to play with it for a few days, but I am thoroughly looking forward to doing so as the reviews have been so good and I've been waiting to return to Yonex for a few years having played with a Head YouTek Extreme Pro for the past couple.

Exactly my thoughts also. I would almost say the Ai feels pro-stock and the DR feels retail versions to give the pro-stock "junkies" something to refer to :)

Tried my DR100s for about 20 hours of play now. The result - I'm sticking with my trusty Ai100s.

I prefer the Ai feel, and there's zero improvement in performance.

Initially I couldn't tell any real difference in the feel. I put it down to the fact that I string my sticks at 65lb and at that tension most sticks will feel like a frying pan. When I snapped a string I decided to reduce tension down to 57, and also cut out some perfectly good strings in one of my Ai's to see if I could feel any difference. I could. At 57 the Ai has that really nice dampened feeling, whereas the DR feels just that little bit harsher. When I went back up to my normal tension I could feel the difference, but not as much.

Don't get me wrong, the DR is a great stick, but so is the Ai. It simply comes down to personal preference, and my preference is the slightly different feel of the Ai.

In terms of performance it's pretty much identical to the Ai, and I can't help thinking that those who upgrade from the Ai to DR are simply paying for a new paint job.

I'm using Solinco Tour Bite 1.20 btw.

That, plus a new feel.

I have not tried the 100 versions, but on the 98s, I prefer the crisper feel of the DR 98 to the flexier/muted Ai98 feel.

From memory on the long Ai98 thread, there were more comments about the significantly flexy/muted feel of the Ai98 than the Ai100.

Have not tried both AI or DR but I thought both rackets should be similar since spec and mold are identical.
New material won't give different feel in my opinion and DR's crispy feeling might be derived from new grommet system. In lafino' review, Yonex representative explained about new grommet system which looks like same as vcore SI's BT hybrid grommet system but Yonex did not clarify new grommet system for DR.

I thought vcore's BT hybrid grommet system will give significant impact but it was very minimal.
If DR's new grommet system is same concept of BT hybrid system, AI and DR will perform exactly same but just different feeling from DR grommet system.

I had AI and DR 98 tested unstrung at tennis warehouse store. the AI i had was 293 sw. the DR's (they tested 8 for me) were 285-290. Odd, because TW lists the DR has having a strung SW a few points higher than AI, but my AI was as many as 7 points higher unstrung. Not sure how those numbers hold up once you throw in string

A friend of mine measured his DR and the SW was 331 strung. Tw is not accurate at all on many occasions.
 
@DJTaurus - I spoke to the guy who does the matching at TW a while back and they take an average of all the frames they get so sometimes due to quality control variance, you get a one that is higher or lower than what they spec.

Poly strings usually add about 30 SW to your racquet.

I currently use a prestige pro ig with genesis typhoon. As I get older I feel I might need a racquet with a little more pop. Will the 98 dr provide much more?

I have an on again, off again thing for the Ai100. Bought 2 Ai98s for my wife after APD tennis elbow. Too muted for her and tried YPTP, gut/smooth pol cross, STB. Enter 2 Ai100's. She never gelled with any, so all sticks went in closet.

Coming from 18x20 6.1s I tried the 98's, leaded up to 340g, 6hl with rubber band and OG. All string combos tried above but 16g or 17g Cyclone was pretty darn good. I play 75% dubs these days and the Ai98 sticks have decent power but you have to really swing it. I'm about to sell the Ai98s...which by the way, in pure stock form and strung with ALU pwr, are within 1g of each other (around 326g). Enter the 100s.

Add a leather grip to these, a few grams of lead between 10-2 and an overgrip for 341g. Cyclone works well to brighten up the feel. Plenty of power in volleys vs. the 98 while I think the control is about the same when taking a full stroke from the baseline. Nice spin, and slice too at this static weight. The 100 serves better than the 98, period (spin and flat) and brighter too as the the 98 is just muted to me on all shots. Not my bag.

So STB is going into one of the 100s as I picked up again today in practice (over my leaded up Ps97 & lightened up RF97) and hit it/served with it ++. The Ai line needs crisp poly and some lead, IMO, but is great on the joints, delivers power, precision, serves and it volleys well. I'm racquet schizo again. DR's? My head wil spin off!
