this really is a great topic, and it could be a heavily debated one, from both sides. i have shot deer with everything from a 52 lb recurve in 1973 to a 104 lb martin jaguar in 1981. i have settled on 64 lbs which i have been shooting since 1981 .ive shot 13 bear with a bow and the draw weights ranged from 64 to 94 lbs.moose i havent had that oppurtunity yet but i will shoot in the middle 60s. getting much to old for the high weights now. with todays technolgy, in my humble opinion a 65 lb bow with the right arrow and broadhead combination is more than adequate to take any of the north american spieces , given the shot is taken at ethical hunting distances for the game sought. the key here is ETHICAL DISTANCES. this will make another great debate topic. strings [as in bowstrings]
