I have been playing with the Fischer Pro One 98 (SL) for about 2 years now. I play well with them, and I don't have any arm pain or anything, so I'm not looking to PK for that reason. But I've always been intrigued and I know PK has a cult following. I'm interested in trying one out, just to see. I play pretty well with the Fischers, but would like to see if there's a frame out there that might give me a boost -- maybe a bit more pop on my serve or a bit more spin or something like that. I'm about a 4.0, with mechanically very sound strokes. I like to play baseline and I like to dictate play. I'm a not a particularly skilled volleyer. I like to (try to) serve big and end points pretty quickly. Is there a particular PK that folks would recommend toying around with? I know the Redondo is a classic, and I did actually demo that once way back when when. IIRC, it didn't feel quite as "buttery" to me as the Fischer, but it was a while ago, so maybe I'm not remembering correctly. Anyway, something really solid would be good, especially on off center hits, but which still provides that nice, soft, cushy feel. Suggestions welcome.
