Last post for me on this. crossBOW hunting is bowhunting. Not because of the draw and holding factor but the fact that you still have to get within 40 yard of your quarry for an ethical shot. And closer is even better.
As I stated earlier any advantage the crossbow has at ranges beyond that are negated by both the noise of the crossbow and the reaction time of the deer.
I do acknowledge your use of traditional equipment of 45# and 48#. Now THAT is truly bowhunting if you're basing it solely on the physical ability to bring the weapon to full draw and holding it there. Up until a couple years ago I use a 50# Jeffery take down recurve.
