I know that in the years past bow were no where near as fast as they are today. That being said what is the slowest you would want for a hunting bow. All my shots are within 30 yards.
I have a 2013 Elite Hunter 60 lb weight and 28.5" draw. I would like to crank the bow down to 55 pounds just because it is easier to draw at that weight. I can shoot a 70 bow repeatedly with ease.
