When I first got my TBT board, I was really surprised of the insane edge hold. I had my old flat board sharpened just some weeks before the TBT board, and the edge hold was way stronger in TBT, even in skidded turns. After a while I somehow got used to the fact and learned to make turns that did not look like I'm snowboarding on a sand paper. And yeah, these experiments were done in icy conditions.
