I've happily played 5-6 Volkl's at the 4.5-5.0 level for many years and they are fine products, BUT I don't believe they produce weapons and advantages at the 5.0-Pro level that Pros need and get from the Wilsons, Heads, Babs, etc. They are generally great control frames and very comfortable but if you're trying to play 5.0+ or something like age group national level, you just can't get there with Volkl. The C10 Pro Tour (93) is the closest one i've found if you can find it, that can hang in at this level but i'm in process of switching to the K90 Tour and it does have the slight extra heavy ball needed in high level har-tru, no Volkl is stock form can do that. Of course $, marketing, distribution contribute but Volkl's just don't help create advantages at the highest levels of play, and that's what you need-just the slightest advantage or short ball to construct and finish a point.
