Not sure if this belongs here or in the string section, but I need string suggestions for this stick. Right now I have it strung with Head FXP Tour, and it feels like mush. It came with my racquet, so that's why I put it in. I feel like this racquet needs a little bit of a stiffer string. I don't need anything that is super textured, as I already get enough spin from the open pattern. Any suggestions? Multis, polys and hybrids welcome. Thanks.
