Man, that is awesome. A suggestion, use the lightest bow of the 3, tune some arrows to it, and shoot it exclusively for a while. You're eye will become attuned to the flight and you'll be ready to go in no time. Shoot at tennis balls thrown around your yard for practice.
Shooting well enough to hunt isn't that difficult. You just need to have a consistent form. If you haven't already, go to the Shooter's Forum and look at Terry's form clock.
Good luck, and post some pictures of those bows.
