This reply is for Scurvy, who had asked if anyone had used FX Sails. I have, and have been very pleased with the results. The workmanship is first rate, the price was good, and the boat sails better.
It's a loose footed main, by the way. There is absolutely no reason to get any other kind. They are easier to trim, have better shape, and better to reef. If the end plate effect did anything at all, the big time racers would be using bolt ropes on their booms, but in fact they are just about all going loose footed.
