I have been researching soft strings that are lower in power than most soft multis. Strings that will soften up a powerful stiff racquet like a Pure Drive, APD or Head Extreme. Here are some ideas I came up with. Please let me know if you agree with my choices and if there are any I missed. Head Rip Control Head FXP Head FXP Tour Wilson NXT Control Isospeed Proff Classic Mantis Comfort Syn Head Intelligence TF Multifeel I am currently experimenting with strings in my Pure Drive 2012, since I don't want to risk poly in such a stiff frame. I currently have it strung with Xcel mains and Evolution copoly crosses and its pretty good. Next I will try FXP Tour and then NXT Control.
