I just was doing some minor tweaking to my stance before i go up to Killington this week (tuesday and wednesday) and was realizing how extreme the setback on my board seems. I haven't noticed how directional it was before. How do you measure setback? Also there are 8 holes for binding screws in the back foot and only six for the front foot. How do you set up your bindings on a board like this? I've always had them more centered with the length of the board and it's ridden fine but i feel like it could be better. I found a website that said the 145 version of my k2 spitfire (think it's 2002 or 2003) was 1.9 cm setback. My board is a 155.
