So I bought a 2010 Custom V-Rocker and I've been wondering if I should buy an EST Binding or just get something else. It's really bugging me that I wouldn't be using the board to it's full potential without an EST binding. Basically, does the EST system make buying Burton EST bindings worth it? I was thinking Cartel ESTs, Union Forces, or Flux Feedbacks. The latter two with the conversion discs.
