RE: Light but Durable lightwind Cam sail - does it exist?
I have an 8.5 Ezzy (2004) that I love. It is quite powerful, easy handling, stable, and of course durable. It doesn't seem heavy at all to me. I got it fairly cheap used, but because it's an Ezzy it was still good as new.
I used the 10.5 Ezzy once and found it lighter than my 10.6 race sail at the time. So I think you would be fine with a 9.5 Ezzy, if you can find one.
