Good advise.
In addition, I'd say that shooting a bow instinctively is more like shooting a shotgun than a rifle. Your goal is to hit where you point. Like a shotgun, you'll shoot better if the bow fits you. The shape and height of the grip, the location of the arrow rest in relation to your bow hand are all factors in shooting well. If the bow doesn't fit you, you will struggle to shoot it well.
Point is. Try several bows before you choose. You'll be surprised at the difference.
