Shoot Randy--I've seen you bust clay pidgeons one after another (not thrown folks--he's good, but not quite that good yet) with a "cheap" wood bow. I have no doubt that with a little time you could shoot a broom stick strung up with bailing twine. HOWEVER.........
As anyone that's been in this sport for any amount of time will tell you, 90% of it is mental. When you are more confident in a particular piece of equipment, you will shoot it better.
I've shot with a guy that, if you took said broomhandle and could convince him it was a particular brand bow, I believe he'd shoot it like a champ. On the flip side, I think if you took the top-of-the-line of one of his chosen few, but convinced him it was something else, he'd have trouble hitting a barn from the inside.
Bottom line is accuracy isn't built into the bow--the monkey behind it is what makes the difference (or in your case, the ape behind the bow :D ) Sure, some are a little faster, some have less shock, some grips fit some people better, etc. etc. etc. but the biggest difference (in my opinion, of course) is the archer.
Give yourself some credit bro--you are just a dang good shot and have gift. Get a little more tournament experience under your belt, learn to loose the pressure and just have a good time, and you'll be the one they are talking about having to beat.
