Wow thanks for everyone's input, I learn something new everyday
I posed the original question because eventually I want to get a board with a larger SCR and in carving photos I am really amazed to see how much riders can decamber their board. I was confused and thought I was forgetting to do something if mine isn't bending like that.
So tell me if I understand this correctly: the board doesn't bend because of something you do directly (like muscling it), but it bends as a byproduct of angulation, inclination, and the force going into the turn.
When I'm on the mountain I do all the drills mentioned and they definitely work. I had to stop and take a picture of this heelside from last weekend in June Mtn :D Admittedly, I have a similar problem as BradBrad. My first few turns are good but I gradually pick up so much speed that things get sloppy and I skid to reset the exercise.
