Don't wince, Yamaha has been using synthetics for years. I have had long conversations with Kent Webb regarding the durability of this material, especially since I don't want to be replacing leather substitute any more than I have to. He is of the opinion that escaine won't repeat the problems that Corfam presented (Baldwin certianly doesn't want to go through that again!) and the verticals I've been working with for the last 7 years seem to be fine, pseudo-leather wise. Warning: *Shameless Plug* Check out my Corfam replacement article at http://www.planet.eon.net/~atonal/atonal/techdoc.html The grands have and always have had genuine deer-hide for knuckle material.
