I currently play with a single PSC 6.1, I am kind of developing a thing for discontinued rackets, so far only Wilsons though. After a quick search I haven't really found anything very detailed on the specs of the PT280/630 can anybody post some. What I like about my PSC6.1 is its manouverability, its pretty head light and I think the power is ok, I just have the problem that its stiffness requires me to string it quite low so I don't get the best control out of it. I understand that the PT280/630 is a more flexible frame. Can anybody tell me of any similarities between the two frames (if there are any) or the key differences.
