2 Kason TSF 200 1 NS9000 X 1 AT700 All strung at whatever tension i strung it at ( i try out new strings/tensions on occasion) . I use whatever has string and feels best in my hand that day. I am not too picky about the racket i use on any given day.
I alternate between my two Sotx Woven 8a's. Both have the same string & tension, as well as the same grips.
I have six racquets in my bag. 2 Ti10, 2 Armortec 900P and 2 Nano 9000X. But I only use one pair of the same racquet when I play so it wont also affect my timing.
So most of you guys also use just 2 racquets at a time (except Dinkalot who uses 6???). Just trying to justify to myself how I can buy more racquets
