well ,I don't know what conditions and circumstances call for with your hunting but personally ,I, would never even consider less then 8x42s.
my glassing usually involves seeing miles, not mere yards or feet.
if you are always in heavy brush and cannot see far distances, less may work fine for you. my thoughts on this is basically, don't settle for what works MOST of the time. much better to have it and not need it then to need it and not have it.
