I'm still sorting out my riding also, and one thing I found with the standing up riding in attack position is that I started really grabing the bike with my lower legs and then moving my upper body around as needed... Exactly like riding a horse, squising with the lower legs, creating a solid base, then post up off the saddle... I also found that keeping my heels slightly downward, as if in sturups with he tips of my feet always on the controls works awsome for me... I found in the past that i sometimes would ride with the toes on the pegs and I'd be loose with the lower legs when you tighten up you have better feel and better control...
