It seems to be a pretty popular frame indeed amongst the pro players. I simply wondered - why? What are it's great attributes that the pro's so appreciate? FWIW at around the 4.0 level, I've known a few ppl (including myself) who have found it to have certain qualities but equally certain drawbacks (mainly in the control area and lack of stability areas.) It's definitely not the easiest racquet to get used to IMO. Anyway, I digress... what's the attraction for pro players?
