Or... just do all your shooting at the pro shop.

What are you doing differently at the shop? You're asking someone to watch your form while you shoot. Therefore YOU pay more attention to your form.

Actually, in many cases, the guy is right. Getting the feel of a new bow and tuning it up generally makes you pay attention to your form and straightens out little shooting flaws. Only problem with that theory is, PaBowhnter would be a World Champion by now if it always worked.
