RE: Backing down limbs?
I would buy a 60 lb bow it will be much more efficient with the limbs bottemed out. If you want a few more pounds you can twist up the strings and cables and gain a few more pounds that wayand there is a good chance it will be a little more efficient. I agree with Danny45 the bow will probally be much quieter if the limbs are bottemed out. Remember also that if you order a 60lb bow it will probally come in a few pounds heavy around 62 or 63 pounds.
I hope I helped.
