I'm a beginning player having just bought the Yonex Ezone 98 Xi. I love the control on this racket and excellent power and pretty big sweetspot. However the weight is a bit much on serves. I cant seem to flick it that good on serves. Now I demoed the 98 only and last few days thinking I should have gotten the lighter 100 Xi. Anyone played with both? The 98 is 11.5 ounces and the 100 is 11 ounces. If I change to the 100 and lower swingweight is it going to be a really big change on my serves or just I just hit the weight room some more. Thanks for any comments.
