For my nickel's worth...
I have some physical issues at this time which have me limited.
(Right now I'm hunting a little over 60# and it's frankly a hard pull at times.)
But, even before this, I would purposely buy 50-60# limbs on all of my hunting compounds. (Recurve/longbow would be in the 45-50# area.) I shoot all of my bows maxed out as I feel, even with modern pivoting limb pockets, a bow still tends to feel better at the shot when maxed. Also, even with parallel limbs, bows still lose their factory specifications for axle to axle length and brace height when the poundage is turned down from max. (The A to A tends to get shorter, while the brace gets higher, which translates into a slightly longer draw length that often negatively impacts shooting accuracy.) My current hunting bow actually maxes at about 63#. This is how I've shot for years. Mind you, when I was still an archery technician, I was daily working on and pulling 80 and 90# bows without batting an eye. (150 to 200# crossbows without a cocking aid too.) It was simply a necessary part of the job. I had no problem with it. (I was generally the "dummy"
who got roped into working on the heavy bows because I was a big boy.
Over time, just experimenting with different bows at different weights (it got slow in the shop sometimes LOL), I simply found that if I could steadily hold and aim, say, an 80# bow for 30 seconds before feeling the need
to shoot or let down, I could steadily hold and aim a 60# bow even longer. (Perhaps a minute or more.) It didn't matter how strong I was or how comfortable I was at a heavier draw weight. I was always
even more comfortable and even more steady at a lower draw weight. (While somewhat relative to the individual, it is still a constant principle. It doesn't matter who you are.) Unless you are really getting down below the 50# mark and/or into really high let-off at full draw (more than 80%) the chances of your draw weight being so low at full draw that you can't hold as steady on target as you would with more draw weight is highly unlikely. (Indoor target shooters deal with this... Dynamic set-up... The need to actually balance the physical weight of the bow itself against the holding draw weight of the bow for their own maximum steadiness of sight picture at full draw. We simply need to be able to shoot a ton of arrows as steadily as possible. By contrast, bowhunters are simply above this balancing act of weight range. Even younger/smaller/female bowhunters who are shooting lower draw weight are still, generally, pulling a weight that is higher than they would for target shooting. This is where some relatively comes in. But, as you see, the principle is still there.)
For me, I tend to only hunt whitetail and smaller game. (Though I did blow right through a 500# Russian boar with a 63# Mathews Outback.) So, I know that 60# is more than enough to take down anything I may encounter. Therefore, that's my hunting weight. I don't need to consider anything else. The fact that I may be able to comfortably pull significantly more draw weight does not enter in. If I hunted a lot of elk, for example, my hunting weight may be 70# based solely on the larger game. If I regularly hunted even larger game such as moose and large African game, my hunting weight may be 80#. But, that's how I look at it. I ask, based upon personal experience and the anatomy of the given animal(s), "What is the weight at which the game I pursue is able to be consistently and cleanly taken?"
The answer to that question dictates my hunting draw weight and nothing more.
