I think im gonna have a hard time getting my hand on some c60s, but how stiff are they.. ??.. dont think i want like rock hard bindings !! ^^..
They're quite stiff and responsive. One of the stiffest out there as far as I know. I ride them often, and I have for the past 3 seasons. I can still butter, jump, etc. on them so it's not like having you legs welded to the board. But when I want to rail a turn they are VERY good at telling me exactly what the edge is doing.
That's why I think they'd be a good match for the camber Custom X. It's a stiff camber board designed for hard charging, and these are the bindings to match.
Not to say that other options won't work, but in the Burton EST lineup it'd be the one to get for hard charging.
What size boots do you wear? I'll have a look and see what I can find for the C60s.
