Hmmmm, back when I got into archery (about 50+ years ago) most everybody hunted with and effectively killed big game with bows in the 42-45# range. They would be interested in the idea that it wasn't enough. Howard Hill shot heavy bows, we all know that, but he also said that a 45# bow (and if memory serves me--dpubtful at my age--I believe he actually said 40#) shooting arrows of at least 450 grains would take any animal in North America. I think I would go with his opinion until somebody with a higher body count proves otherwise. I used to shoot bows in the 50-58# range but mt body, at 69 years old, tells me it would much rather I shoot bows in the mid-40s. I have excellent results with them on deer, bears, and feral hogs.

As I stated, it was my opinion, I dont claim to be a authority like Hill or Bear and will never come close to their records. My point is: if you choose to shoot traditional, then put in the work it takes to shoot a traditional bow. one of the constant themes of discussion here is "Whats the least amount of weight I can shoot and kill something?" if that is someone's main goal, then shoot a compound.
