First, while I think draw weight has a lot to do with this, there's more to it. It has to do with the whole learning curve and how I went about learning.
Second, to put things in perspective, some are big and strong and others, not so much.
I' 5'7", 145# and 56 years old. I was always "athletic"...wrestled in high school, mucked stalls and did other tough barn work while learning to shoe horses and have shod horses professionally for about half of my working life. I still do fairly hard work.
After leaving the compound world the first recurve that I stuck with was marked 55# @ 28".
From there I went to a 65# long bow and then a 65# long bow. I packed that bow for a LOT of years.
I killed some stuff and shot well enough to get thinking I was pretty good at times.
