I definitely wouldn’t go as far as saying that these light, fast setups are inadequate, because used properly, they work just fine. But it’s something to think about when you are setting up your arrows. Personally, I prefer to shoot an arrow that I know will blow through the shoulder of any moose or deer I could hope to encounter, should my shot be slightly off its mark. A re-hashing of what shot angles are ethical is a can of worms to open up another time, but if you properly select your equipment, the “accepted rules” become much more flexible and forgiving. I would encourage folks to always be selective in the shots you take, but also use equipment that gives you the best chance of quickly killing and recovering your animals, even if you don’t quite hit your mark.
