For the guys who have some of these vanes to try out, what kind of resin are these vanes made out of? In the pic the look like they MIGHT (you can only tell so much from a picture) be made out of the same stuff that AAE vanes are. I'd also be interested in how durable these vanes are. It looks like the fin might be the 'weak link' - is it easy to rip the fins off the vane?
