I've been using my DR98 for about 2weeks now. This is a good stick, the control is superb. It has low launch angle so it take a while to get used to it specially coming from Pure Aero Tour and APD GT 2010. The feel is muted, adding dampener may have negative effect on your feel as it will feel so muted that you can't connect to the ball, don't use one if you want a balance of feel and dampened feeling.
My only gripe on this racket, and I messed it up big time, is the grip. The grip itself feels different maybe because of round shape, then I replaced the stock grip to wilson leather grip w/c I usually do on my previous racket to enhance the feel, but that's when bad things starts to happen. The stock grip is so thin and so light, that adding a leather grip will increase the grip size, plus the overgrip it may feel increased a 1 full size. The weight of stock grip L2 size w/ finishing tape is 9g only, compared to babolat's around 16g, so adding wilson leather grip's 22-23g, it will significantly increase the static weight and increase HL significantly on DR98, this will result to little room for further weight customization if you are targeting a little over 12oz and no chance if you still want sub 12oz. I customize it further adding 1g at 12o'clock, 4g total so 2g per side on 9 and 3oclock position and gave me 12.2oz or 346g strung (306g stock grip unstrung). It still feels unbalanced to me so I want to bring back the stock grip, but it's messed up a little, yonex glued the stock grip tightly on handle like they paint the glue on the handle and no adhesive tape attached to stock grip, some of stock grip is ripped a little trying to removed it before. So please be aware when removing the stock grip as it's very light and thin, I'm waiting for my kimony techni leather and hopefully this will do the trick as it's thin based on their website, and also light.
One more thing, please somebody confirm, the handle w/o stock grip is bigger than babolat and wilson, that's why I thought they attached very thin stock grip to make it similar in size w/ other racket brand, and that's when I thought babolat's grip is bigger than other brand. The round feel of the handle is because the bevel 2 and 6 is shorter compared to babolat so it's easier to feel (using leather grip) the bevels when switching to grips during play on babolat's grip, or maybe this is the effect of grip suddenly became bigger that's why I can't really get the feel of bevels on DR98.
Overall, the racket is good it's just tricky to find a similar thickness and weight replacement grip if you plan to change it specially if you're gearing to leather. Btw, I don't know the exact thickness of stock grip, and can't compare to other thin synthetic since I don't used it, but for wilson leather, feels like wilson is twice as thick or 1.5 thicker, but please correct me or give us some thickness details.
