Yeah I think thats my mistake, because I never had this pain when I used this racket before so I do think I took away what little shock resistance there was. My 93 has leather, but being made of a quality graphite makes the difference.
I can get a Bio 300 for a good price, it looks a decent racket and seems to suit my style pretty well, so I might as well do the sensible thing and get one.
