just like the others said go to a local bow shop, many bow shops, even if you have to travel. shoot as many bows as you can try them all out. dont think of anything but how each bow feels to you. get the one that you are most comfortable with. the one that just feels right. dont buy the first bow you touch. look for a bow in the 55-70 lb range. then talk to the shops and see who is more then willing to go the extra mile to set you up even if its not the nearest shop.
hope this helps.
