I strung up a full bed of grey typhoon last saturday. This is one of the best polys i have ever hit with. Perfect spin level and it is soft. I used the racquet tune app to measure tension for the fellow TTers. Off the drop weight - 61#s In bag until monday - 59#s After 2 hours of hitting - 55#s After 2 hour hit Tuesday - 55#s After 2 hour hit tonight -54#s This is definitely a winner for me..great stuff..is there any poly out there that compares? The only complaint is that i can not get it in 17.
