It's kinda funny. I heard the same story but that it was Frank Moore who did the return snap at the trade show. Rumors you gotta lovem.
As far as the snap-tee it works great but i still prefer the single spey or a reverse or left handed spiral- roll. Especially the spiral sroll it generates a lot more power than the snap-tee. I especially like it in winter because it gives me the straight across stream angle that I want where the snap tee or single spey gives you a more downstream angle. Of course all that can be modified easily so it ends up being a matter of personal preference.
