Just to match the tone put down earlier. Yes lets start a new thread, where we can measure our dicks, because this is no longer helping cootcraig. This is about flexing our brains/muscles, strutting and posturing, in short measuring our dicks... But alright im game, i got a big one
Flexing the knee joint CAN create twist, but only if you ankles, and hips move too. I can flex/extend my knees all day and keep a flat board, if i so choose. If you want to create twist, more is going on. As far as pushing down on your toes on toeside, this is a big problem with alot of riders, not denying that, but it doesn't prove your point about rotary at all. After you mention that you say you are isolating a movement. Great! But you forget to say what movement
and if flexion in the knee is the only one, without moving ankles, or hips, thats not very good advice. Prove it? Well the proof is in the pudding. Stand up from your computer right now (get away from all sharp objects) stand in your snowboard stance, now only bend your knees (NO you cannot flex your ankles, or bend at all at the waist because i am trying to isolate a movement here. You fell over didn't you? you should have beacuse its like doing a wall sit without a wall, you fall.
Now as far as rotary on steeps, and in bumps... You are cordially invited to come to any mountain, and blow out especially heelside, because your beloved rotary has added too much pressure to the effective edge at a given time, it cannot hold, and throws you to the outside of the turn. Ever have a heelside turn that chatters? (we all have dont lie). Thats your beloved rotary at work. Stay balanced, stay aligned, use your sidecut for what its worth...
I propose a few guidelines for you MGD81
1: Don't be a dick, EVER
2:If you cant follow #1 at least be right, or be funny.
