Concerning the "wait and Sprint" style, I think it is more effective on courses that are not as standardized as here. Especially when they UNDULATE like the Rise (see, I'm learning). If a horse didn't save any energy after running up hill he would stop dead. Our Steeplchase races run in the same sprint it out at the end style and most of these are run on varying terrain. I can't honestly say one is better than the other, per se.
