So I finally chosen the board I want which is the 2010/2011 Arbor Roundhouse Wide 167 but now I'm stuck on the bindings. So it comes down to the Flow M9 or Union Asadachi III bindings? Im a all mountain rider. I like to bomb down groomed runs and run through the off trails/trees. Let me know your opinions, thanks. Also, if you have other suggestions I'm open to them but would like to keep it within REI store.
