What is the dominant factor in TE development - racquet or strings. I have bad TE due to prob using the most idiotic set up the roddick pdgt and a full bed of poly ranging from msv fh, cyberblue, and bhb around 50lbs. When I am loaded with motrin and have had a few days off you can do a lot with this setup and a live arm. I have asked for roddick substitutes that are arm friendly and will give a few of the suggestions a shot in demos but a lot of people insist on dropping poly. I have used multi and done for them. This has made me wonder what the dominantfactor in TE. Can a pro kennex have a full bed of poly and be worse than somerubber stiff racquet with gut?
