My guess is you don't need a 16 DIN binding if you riding 171's. Not that you aren't good enough for them, you just aren't big enough for them. For a high end binding you can't go wrong with the FKS/Pivot 140's (Look makes the Pivots, and Rossi makes the FKS, but they are identical bindings). I've ridden these on my main ski and love them. This binding will last forever... Seriously.
