With proper form there is no difference in point-of-impact with either. 20 yards is 20 yards. 30 yards is 30 yards.

Simplify your setup and shoot a single fixed pin for hunting. Or, if you want to try like I do, then buy an adjustable sight for 3D and target and when hunting season comes around then set it for a fixed distance, say 20 yards, and leave it alone. Shoot to about 27 yards with a mid chest hold. BEND AT THE WAIST.
