A bow is smoothest when the shooter can control the shot. Many people make the mistake of going as high as they can on the poundage. But if you are at 70lbs and it is difficult for you to draw during practice, you'll have a heck of a time during a hunt.

Remember you're sitting still for hours on end so your muscles are relaxed and then you have to immediately pull the bow back, silently mind you, and sometimes hold it for a great deal of time.

Always go with lower poundage and work your way to higher if you want too... Never start the other way around.
