Bought a good, used kps 88 from one of the seller's on this message board...just wondering if there's a difference is grip shape vs. the other wilson racquets? I use a k90/blx 90 w/a 4.5 grip size and the bevels are much more defined...the kps 88 has somewhat rounded bevels, different dimensions all together and feels a touch smaller than 4.5...? Kinda bothered by this, like the grip/feel to be uniform.
