RE: Biscuit vs open rests
turtleshell - I use right helical and love it. It seems feathers hold up better but the plastic does just fine. Back when I used a Bodoodle Pro I still changed vanes out. If you shoot any at all you will wear out vanes one way or another.
The WB is no different than any other rest in that you need to tune your bow for best performance. It is different in that it is more forgiving if tuning is not at its best. As far as noise, yes, I've gotten noise from mine (yes, I have the correct size biscuit). Using xx78 Superslams I got some pretty good noise. I waxed the alums and it seemed to get rid of the noise but I ended up going to Beman ICS Hunter Elites and get zero noise. If you shoot alums it might be a problem. I love my SS's but I can't complain about the Bemans therefore no problem for me.
