How do the Volkl 98 sq. in. headsizes compare to the Wilson 95 sq. in. headsizes? I know that sounds like a stupid question, but I know that a Head 98 is basically the same as a Wilson 95, yet a Yonex 98 is closer to a Wilson 100. So how does the Volkl 98 compare? I've never used a volkl, and am curious how they size their racquets.
