In states with multiple kills allowed, bucks and does, a tight blind with a shorter draw might be the proverbial ticket.
I have a knack for bringing the wrong bow to the fight, so I am settling on more length, 55 and up. I still can not see 69-70" working from a kneeling stance.
As an detour, I made a little 50 incher, 18" or so draw, 55#. Ok, so what...
I practiced holding arrows in the bow hand and shooting close, 10 yard close, like southwest Indians might do attacking a muzzle loading bunch of fellows, rapid reloading. That type of weapon had merit.
