Thinking of buying my first split setup. Found a good deal on a G3 Black Sheep, w/ Spark Blaze bindings and Voile hardware. It's setup for goofy, with an odd stance angle. Before I buy, wanted to make sure I can easily adjust it to regular, and then switch the stance angles. This is doable with this setup, correct? Also I'm 5'10 145#, and trying to decide between the 158 and 162. Planning to hit mostly pow in Montana, and probably at lower angles to start, so leaning 162. Advice for sizing would be good too. Thanks!
