RE: Low KE Mech
A have a buddy who refuses to retire his old bow. In 1988 it was state-of-art. Today is just art. He thought he could upgrade the bow by going to a mechanical. He is shooting 27" draw at 56lb. Long story short, last year he stuck a very nice deer, and the arrow did not penetrate for a kill shot, but wounded a deer we could not find.
I agree with majority of post: Go to a cut on contact style broadhead.
