I shoot a 80lb guardian with a 500 grain matrix arrow, the bow is quiet and forgiving BUT this winter when it was 10 freakin degrees I could not pull that darn thing to save my a$$. I'm a pretty big guy but you have to find whats comfortable for you in diffrent situations. Inow have a 84lb commander backed off to 76lbs for the freezing temps and my screaming 84lb guardian is for spring and early fall. Just cause you can lift a smallblock out of a car dont mean you can draw that 80+ lb bow and wait for 2-3 minutes for that big buck to turn when its frozen snot city.
