ARGH. Yes, try before you buy, best idea - boots AS WELL as bindings.
SO - I rode for awhile , maybe 6 hours on weds, hit a super pipe for the first time in my life, took about 3 runs at it, then noticed that the buckles were coming unlocked.
Well at the bottom of the superpipe was a flow booth (along with other manufacturers). I stopped by and they pointed out:
1. that the bindings were too big. I shouldnt have taken the advice of the EVO people saying that I should have taken size XL's, even though flows own charts say size 12 = xl
2. a screw holding the back was coming out, and at speeds that may not have ended so well as the board flayed into my face. ha.
Evo wont take them back because there were ridden, so Im kinda stuck with them.
I rode on them for about 9 hours weds. All in all I kinda like them but I'm either in too tight or too loose. At times more difficult to strap in than my standard bindings which I've gotten very used to and never have to sit to get into. I'm pretty quick with them but wanted something quicker.
