imho, it's a well placed sharp arra of reasonable mass weight that kills game at reasonable distances, not the bow.
each of us gotta figure out what works best for both the short and long term of bowhunting and pulling string.
i always get a better release and "feel" when i'm holding 55# or so at my draw length, it's what i've always pulled, and that's what i enjoy to hunt with these dayze. due to a frozen bow shoulder, at times when i do have a physical problem with that bow weight, i drop down to 46#.
i think a 40-45# modern trad recurve or r/d longbow is a good enuf engine for killing small game, deer and hog, at reasonable shooting distances, with 450-500gr matched arras with good sharp broadheads, and good shot placements.
as always, ymmv!
