But what the research shows is that is too lite. If the facts point to a higher percentage of kills, and it quiets the bow noise down, plus decreases the likely hood of any issues of penetration. That coupled with his facts on shot placement, would be a net benefit for everyone involved, except for the dead deer, for him not so much. I wonder what the Ranch Fairy's thoughts are on increased weight and trajectories? Like for shooting antelope on the plains type of ranges. I think for deer and the like, it's information I will use on my next arrow build, and going forward in my own hunting (kill) philosophy. If it's better for the animal I'm all for it, and I'll take the leeway that heavier arrows provide.
