This is the reason why you had issues with board control. Never set your stance forward on any type of board whether or not it is a true twin, directional twin, or true directional. Due to the board's geometry, you are going to have troubles riding with a stance set forward
Wouldn't that make it easier to ride switch? Or would switch be easier if you moved it from the ref. points too? I've got a burton operator wide, (refference = 21. in. stance width w/ .5 in. setback), it's a twin-tip directional, and I moved the stance forward .5 in. last year, and rode with it .25" forward today... Seemed to have control to me, albeit, im not moving it around that much.
Just wondering what physics/geometry really does have to say on the issue.
