Barry I'll go out on a limb and say you are over riding it. Read back through the SF thread (or any other Thirst thread) and you'll find a common theme of not forcing the nose or curb stomping the board - although they will tolerate it just fine, the key is to stay centered and tip the board up high on edge and allow the side cut and flex voodoo do their stuff.
Maybe center the bindings again, and do a few one foot runs on a gentle slope to unlearn the habit. I'm sure Beckmann or others have some useful angulation drills too.
Like Ike Clanton says "Listen, Mr New Hampshire nose doggy, nose riding don't go 'round here!!"
