No one is trying to talk you out of bow hunting. As for your question. They are right about going to a good bow shop. Try to go when they will have time to really talk with you. There is a proper way to measure you for the proper draw length. Maybe if you let us know where you live, we could suggest a good shop for you in your area. If you have been deer hunting for a while and can put in the time practicing before opening day or October, like you said. You can be set up and ready for this season. I have been hunting for 3 years now and still not ready to take shots past 25 yards. I am spot on at that distance but not ready to shoot further out. Have you decided where and how you are going to hunt this year? Ground blind or stand? Shot distance at you hunting sight could make a difference on if you will be proficiant before your season opens.

Just a few rambling thoughts.
