SCOTUS, what gauge V-Torque do you use? I got a couple of sets of 17-gauge in the Volkl poly trial pack, and they don't seem playable in the 16 x 15 pattern (I'm assuming you have a 99S). The first time, I strung it full bed and got about 30 minutes before a break. The second time I put it in the mains with Isospeed Baseline control in the crosses, hoping the smooth crosses wouldn't eat through the mains so quickly. I got about 45 minutes that time. Both times the string broke at the mains, right in the center of the string bed.
Is the 16-gauge significantly better? I feel like I need to get at least 5-8 hours out of a string job just to make it worth my time. I did love the bite of the V-Torque though.
