A little forward lean in your bindings help a lot reducing that back side carve chatter, and engage that front edge faster. I avoided it because it eats up your calves faster, but I'm a fan now. Better turns, more responsive board.
Are you talking about carving heel side? How do you get forward lean in your bindings that way? Trying to curl your toes upwards towards your shins? I understand the concept of forward lean in the bindings when carving toe side.
Tuck that back knee in, after the apex of your turn.He noticed my tendency to open my back kneee toward the tail of the board, when squatting in the middle of a turn, especially heel side...Probably for stability, mostly for bad habit. Even with both positive angles ( +18+12)
The one caveat I can think of is if you have a really flexible board. If it's a super loose board, tucking that knee in too much can cause you to wash out.
