Personally, not sure that FX sails need to worry as much as some about the shape etc. as they are good lower priced sails per say from a few that I know that have them. No not as good as some, but ok.
FX quote for Pentext tri-radial #1 = $2282
Quantum technora string sail #1 = $1960 (shipped)
Q measures the boat and has great customer service. And they worry a lot about sail shape. Get quotes from 5 makers and try to stay local if you can. I guess my point is that every knows FX doesn't make the fastest sails, but FX doesn't seem to want to admit that. Try the big 3-4 names and I bet they can come down on the price and make it worth your wild.
