In terms of being related to each other in playability, what racquet models do to think share a lot of qualities between different sizes? For, example, I think that the Prostaff 6.0. 95 is a reasonable facsimile of the 6.0 85, but more user friendly. They share many characteristics and a 6.0 95player could progress to a 6.0 85 and find that much of what he/she likes is still there. Or, a 6.0 85 player could move to the 95 if he/she needed a less demanding frame, but still retain a lot of the positive attributes of the 6.0 85. On the other end of the spectrum is the Diablo mid 93 and the midplus 100. Both thin-beamed, basic frames, but other than that, they really just share a name. I don't see a lot of continuity and I think they play completely different. If I ever moved away from the Diablo mid because it was too demanding, I wouldn't move to a Diablo midplus. What do you think?
