I just purchased the Kirschbaum 17 polys and the Tecnifibre X-One Biphase 16 and i cant decide whether I should put the polys on the mains or the crosses. I use K90's and im not a big string breaker, anything i put on usually lasts me as long as I want the string on my racket. What do you guys think i should do. Any comments are really appreciated.
