I would check if there is an archery shop in your area and try a few used bows out to see what would fit you proparly. Some of the shops have indoor archery ranges and can give you some great advice. Also visit the archery forums as some great advice will come from there as well. There is nothing wrong target practicing while waiting to take your hunter safety course. Just keep asking your questions even if it may appear kind of stupid to you as there is no such thing as a stupid question here. Good Luck on what you decide.
By the way welcome to the forums.
