Harrisnmo, I'd pass on the haul into the backcast - no need for it as the extra heavy head will load the rod just fine and you don't need much linespeed to backcast the 20-30' of head. In fact, you're better off to make the backcast as slow and easy as possible. You don't need the speed, and the less velocity the line has when you reverse its direction the smoother your cast will be. The final cast is where you want to hit the haul.
