In my opinion if you are kind of new to shooting alot, or are not very technically knowledgable, I would get a 1 1/2, and i would make it long. Depends on money but a great bow for an inexperienced shooter is a Hoyt Protec. Long brace height and, i would suggest, a 47 incher. Long, heavy and stable. Takes a lot to torque a bigger bow. It will also really build up the muscles holding that thing on the target. Once you are able to go to the shorter bows (When form is good) they will seem light and you will shot them really well. 2 weeks before a tournament i break out the 47 incher, then when i go to my tournament bow for the shoots, it seems so light. Like weights on a baseball bat. Just what i would do.
