I've used Titan many times as a cross, but not as a main. For years I had no issues with it, even when they were punching the peg-hole in the packaging right through the sealed part (idiots). However, of the last 10 sets ordered from TW, I've had a 33% breakage rate on the machine (happened just last night). Note that this happens in the 1st or 2nd pull, and there is no kinking. I'm not a USRSA certified stringer, but I've been stringing for over 20 years, 15+ of that w/ Gut. I can tell you that it is most certainly NOT me. Tension is 55lbs, pre-stretch option on my WISE. When they snap, I put them aside & use on my wife's racquet, where I can drop the tension to 50 or 52. I will say, though, for the ones that do make it, it plays great. The big issues are (1) stringing, and (2) gauge consistency, although that has improved over the years.
