Good advise as usual, Paul. You didn't supply the draw weight, so I dont know if you will be underspined, overspined, or what. I am sure your bow can be made to fit you if it doesn't already.
What Paul is saying, simply, is that if you are shooting a bow that doesn't fit you, archery will not be any fun for you, and you will give up. By doing so, you would be losing out on the greatest sport on this earth!! As you get more into archery, you will discover that the sky is the limit. There is almost an infinite supply of rests, sights, arrows, bows, and so on and so on.

ps. No need to apologize for a "simple question." I mean, look at Zak here....he's as simple as it gets..... j/k buddy
