Having sailed w/ Ralph for a while this summer, I can verify that the thinner sheets are excellent in ALL wind conditions. The sheets ran VERY easy and did not hang up the sail in light air. In heavy air, the line weight was more than adequate. I can't see a reason for anything heavier the 5/16ths, gloves or no gloves.
