From the riders (well, this rider's) perspective, I find that over-rotation is a function of a couple of things. The cut out and the head rotation. They feel connected, in that if I take a fast cut, with almost no wait at the end of the cut, I had best just glance up. If I go out a bit slower, wait a bit at the end of the cut, a more significant 'look up' will still get me around. More to follow...
The rig may make a difference, and I think it is important to remember that one of our guys went from our rig, detailed below, back to his unpolished pro, and did it again.
