The straighter an arrow comes off the rest and/or the sooner it straightens out, the less chance of it adversely affecting penetration.
As Bowhunter 44 stated:
That momentum would be much better spent following, or perhaps even driving,the broadhead into the target.
Also, said in a different way, the oscillation/porpoising/minowing or any mode of travel from point 'A' to point 'B' in anything other than a straight line will affect momentum/penetration.
This seems like a Deja voo for me Len!!! If I am not mistaken I heard you Schooling Pat Dinan on this same subject last week

No disrespect Pat if your reading this






You Da Man!!!
