well I finally strung my racket with it at 53 lbs. a pro-kennex redondo mid (93). thanks for the advice from the guys here I reduce tension from my normal tension. I usually use either VS gut or Prince Syn. Gut 17 ga. I liked it quite a bit ! the string don't move at all and topspin was way too easy for me, I only use topspin as an alternate shot eg. moonball, but I found myself taking big cuts at the ball with topspin it was amazing, I think because the strings don't move has something to do with it. I bet 17 ga. would be even better. I was pleasantly surprised with this string !
