Most bows that are 60 lbs can be turned down to 50. This is more than enough power to take any animal in NA. I would turn the bow down to start with (3 turns). As you get more comfortable, you can turn the weight up. This is however not really needed, 50 lbs is more than enough to kill a deer.

As a newbie I would also suggest cut on contact broadheads. Magnus Stingers are hard to beat. You will get more penetration with 2 blade fixed heads than any other broadhead (don't get caught up in broadhead hype). This might help if you hit a shoulder (It's most likely going to happen to you sometime).

Learn to bare shaft tune (just ask we can help), and practice and you should be well on your way to a dead deer.

The last peice of advice I can give you is kill animals. Don't wait for a monster, kill small bucks or does first. You really need the experience and the confidence. Even shooting other animals out of a tree stand is good practice (In fact tonight while hunting I shot at (I missed[:@]) a possum running at 35 yards). Shooting any animal from a treestand is good practice.

Hope this helps
