Yes, you're correct, it was Fluoro. I must have been confusing it w/ the 4G you had in your PST (at least I think it was 4G that I hit with).
I get approx 6-8 singles matches, then I cut it out. Other than clay, I've yet to break that setup, and I could easily play longer with it, but I've just developed a rhythm where every 3 weeks I rotate racquets.
