I love the TW boards when it's "new racket" time. I've been searching around for information on a variety of frames and came across this thread http://tt.tennis-warehouse.com/showthread.php?t=78632 It really made things clear. All this time I've been assuming that Kevlar made a racket STIFFER when in reality it makes it more FLEXIBLE and provides shock dampening. I had heard Twaron was another name for Kevlar, which didn't make sense because I love my PT 280/630's with Twaron and they certainly aren't stiff. I also love the feel of the ProStaff 6.0 and I couldn't reconcile that with loving the feel of the PT 280 and Prestige. Now I know they're made of the same stuff. It also explains why I don't like the feel of the POG (100% graphite) but do like the feel of Pure Drive's and Pure Control's with Kevlar. I don't like the Babolat's overall but the feel felt fine to me. I recently bought a Pro Kennex Type C Redondo because the specs were so appealing but did not like the feel at all and have been trying to figure out why. Turns out the 100% graphite construction is the culprit. I have a demo of the PK Type C mid with 80/20 graphite/kevlar and it feels great. Imagine that... My quest for a Prestige replacement just got a lot simpler. Look for the Kevlar (or the fiberglass).
