Soft Bindings For Freecarving
Bindings for Boardercross
C60 were hella stiff, but they are still made for freestyle big Mtn riding. So less stiff then stiff bindings made for carving or such. Pretty sure this is as stiff as you can get: Freeride 2 Pro EVO bindings
Seems like people use a little of everything...
There is a point of diminishing returns. A board and boots can only be so stiff, putting something TOO stiff on the board may not feel any better than stiff freeride bindings.
