Thanks all. Haven't had new sails until now so I wasn't sure on the stiffness and thought maybe because they weren't that expensive it was an issue with cheaper sails but I guess now. .
I have a Force 5, and Intensity makes an inexpensive sail for it, roughly $150. The best class legal race sails by Cullen are $500 or $600. Since I'm not racing it, I just wanted a new, better sail than the 30 year old originals.
So, I mentioned to a sailmaker I know, who also used to race Force 5s, and she said that Cullen does indeed make the fastest Force 5 sail, and the Intensity uses sailcloth with too much resin in it.
Me, I'd rather have a new sail that can be trimmed flat, than a baggy old sail that sucks. So, $150 was fine for my intended use of blasting around the lake on high wind days, planing occasionally and spewing spray all over...
