First off, you will not gain 26% of ke, I do not care what the “Program” tells you. Those numbers are wrong. 10% change is about the norm. Do not make such a decisive decision after only a few hours on the internet. I will gladly give up 10% of ke to use one pin out to 30 yds. I am no fool, and I could lock up your hard-drive if I sent you pictures of all the bucks that will attest to the fact that a light set up is absolutely deadly on deer. I shoot a 365 grn arrow and produce almost 67 ft. of ke. at 70lbs. You are suggesting I need to almost triple my arrow weight to be ethical?????. That is a foolish statement.
One of the eights I shot this year was at 35 yds. with expandable head, double lung, entered through rib, no pass through because it busted into far leg bone. Deer dropped in its tracks.

Here are some formulas for you:

Light + fast = dead deer

Heavy + slow = dead deer

There are very good arguments for both, and both setups are great hunting setups.

My preference, light, fast and flat.
