On the face of it I thought it wouldn't be much different from the CRX lite racket. It's 135g as opposed to the lite's 125g. the previous model lite was 135g and I found that just right for me but for some reason, maybe it's the weight distribution, I just can't get on with the pro. I only tried the CRX pro because I've been so disappointed with the durability of the CRX lite. I've gone through 6 of the lite rackets in the last year so thought I'd try the pro. It does look a lot stronger and the strings are protected by the protection strip (about as useful as a chocolate fireguard on the CRX lite) but that's not much good if there's no feel. So I'm back to buying the CRX lite, plays great but the strings'ill be bust a week!!
