Ink, That is a very common question from people. I am wondering, "Are you big and strong, and how much can you pull now?" I started at 35# and worked up to 45, then 50, and thought, "That's pretty good, but I think I can go higher, just for the hunting power advantage, in case I meet a big hog." For deer and smaller hogs, 40 - 45# minimum.....IMHO. But if you are willing to work a little, why not get more power if possible, as a safety margin?
I'm 42 yrs. 175 lbs, 5'8", and not a particularly strong guy. Cheers
