If it's any consolation, Adam, the work and extra material needed to make a kilt on the diagonal would send the cost of a PV up into the neighborhood of a wool tank, and the cost of a wool tank up into the neighborhood of a good used car. (Even if Rocky was willing to take such a PITA idea on.) That might help you make up your mind about the diagonal idea. I might attempt it if I can get about 25 yards of PV tartan for insanely cheap at some point, but I'd never saddle someone else with the beast.
