Topspin by Cyber Flash (or Cyber Flash by Topspin, I forget which way it goes.) It is 17g and I string it at 57 pounds. The string itself lasts forever and holds it's tension well. I only break a string once every 2 weeks or so with this stuff which is along time for me. 57 pounds seems to be a good happy medium for me between power and control.
What time do you go to bed most nights?
