I agree with both previous posts. Start with a lite weight bow that you can easily draw and hold, without discomfort. The fewer #s you pull, the easier it's going to be for you to get a consistent technique down. Which, without consistency in your shooting form, you'll never get consistent in your shooting accuracy.

Myself, I started with a 50# curve, but was shooting a 70# set of wheels without problems. The 50#s was all I wanted to handle at first and I still shoot a relatively lite bow (54#) as my primary shooter.

When you are consistent in your shooting abilities, then you may want to consider moving up in weight a little.
