So, ideally, as you pop up, what part of the lower half of your body should be the last point of contact with the board before you hit a crouching position?
For me its usually somewhere on my quads just above my knees, but as I said, I think I tend to support slightly more of my body weight on the right side. I'm goofy, so that ends up being my front foot and I'm not sure, but I think having slightly more weight on that side might be contributing to the knee drag.
