I know this is CA but we're talking GOB's and club/beer can racing too right? I've done remarkably well in our local club races with my old pinched fanny US 30 but it's becoming apparent that the old crosscut dacron genoa of unknown age is a limiting factor. I see a couple of sails on the used sail websites that are an almost perfect fit as far as size. One is listed as a North tri radial mylar good+ condition good to 20 knots apparent and the other for $200 less ($395) as a medium UK Tape Drive. I get the impression that the Tape Drive sails hold up well. the good to 20 makes me a litttle nervous. I don't have any experience with either. Opinions?
