Well, I've already stated what I know to work so I won't take up a bunch of posts to argue about it or anything, but it isn't saving any time when you have to backtrack and fix the hard pacing that raising the head will cause.
BTW, I have that book that trailhorserider is talking about; it is an enlightening and informative book, sckamper. It helped me out with a number of things I was struggling with. I really think you'd like it!
