I'm with Rav on this one. I use crow on every plane I own....it adds benefit in my head, and therefore adds benefit to my plane. I don't care what anyone (including science) says, crow reduces the stalling speed of the tips of the wings and allows me to land slower....I don't care about the AOA crap.

Take it or leave it, use it or don't. I like it, I use it.
