Since getting my Steam 99s I've tried strings like Solinco Outlast, Isospeed Pulse, Polystar turbo 15, and Genesis Twisted Razor at tensions ranging from 55-65lb. Guess what, all of these lose so much tension within an hour or two of hard hitting (4.0-4.5) that the racket becomes an unplayable rocket launcher. Big surprise with this racket, right?
So below are the strings that I am looking at trying out now. Which do you guys think has the best chance of holding up tension loss wise in the toy? I string with an electric constant pull tension head (Wise 2086) by the way.
Signum Pro Poly Megaforce 16
Babolat Revenge 16
Tourna Poly Big Hitter Blue Rough 16
Tourna Poly Big Hitter Blue 16 (is tension loss with this string about the same as the rough version?)
