Ive read so many stance posts and setup tutorials im a little overwhelmed. ive been snow boarding for many years but only just started paying attention to such details. And i see a big change in my boarding. I have just bought a new board and ive never given stance a thought. Its a rossignol sushi, a short wide board, highly directional. im not interested in park or tricks or jumps but only in steep tight trees and as a secondary interest, carving, but i can compromise the carving to favor tight trees, quick turns. Im also an old fart, 56 !, but strong and fit for my age, i teach DH mountain biking and work out but still getting older and slower despite best efforts, the sushi has transformed my riding ive rented one a few times and now i have my own. But, how do i set up the bindings? ive measured my kneecap to groud, 20 inches, BUT, im 5' 11 inches. I have very short legs for my height. I chose a 21 '' width, +18 front and - 9 rear. Do i just adjust..say the rear 4 deg each day and see? then try the front? Is it that simple,? just adjust for a day and see?
