BUT, I still feel on the stingray that the older style sails hold their shape better and drive more easily in light winds+chop.
Back in the days of the failed F18HT, Randy built a main out of PBO that was clewless... sort of. He took the material that would be in that area and replaced it with spectra. That sail area was then added to the head of the sail. It really was a cool sail to look at and touch. We all called it "The Fly Swatter" b/c we were just flies on the wall when he had that sail in light-med conditions. The extra sail area up top REALLY paid off and this was square head vs. square head.
