Has anyone had any experience with versions of the new open pattern spin rackets, and if they may actually play well with a non-poly synthetic or multi? Got a demo of the Wilson Six.One 95 spin, but am waiting for the weather to clear to have a chance to try it. Actually it is for my son, who is about to start college tennis. It is strung with poly. He is hitting a six.one 95 16/18 right now, and prefers a hybrid poly/ synthetic over all poly. Wondering with these really open string patterns if they might actually play good without poly, for those of us that don't have the modern extreme topspin games? At some point it seems like almost too much spin.... My son hits spin, but not as much as most 18 year olds.
