....sorry, I think I'm about to hijack your thread, just because I have a question as well. :o
I've been running 90* on both my cant discs (front - 3; rear - 6) and my toeside carves were amazing, but my heelside carves left a lot to be desired.
I originally wanted to make it an outward cant on my front foot, but my dad convinced me otherwise; I changed it to pure toe lift in the front (going from 90* to 60*), with no change to the rear.
First thing I noticed - getting off the lift was a little more awkward; since I had pure toe lift, I was had more pressure on my heelside edge, and generally I kept turning heelside when I slid off the lift.
Second - My heelside turns IMPROVED to a great degree. I noticed I felt more confident, and could get much lower on my carves.
Third - I think I became a little more unstable at speeds. Yesterday I was fine when I was at higher speeds going in a straight line (you need speed to get to the bottom of June from the top of Chair 4/6). I caught an edge randomly, something that wouldn't have happened the day before. I had more than one occasion of sketchy-ness as well, just in casual sliding around.
Is this something that I'm completely wrong on, or is this something that others have noticed?
