I know one thing, I didn't imply anything about good or bad as far as arrow selection goes. What I did say was that kinetic energy and momentum are not the same thing! On the, unfortunately, rare occasion that I get to the pro shop I hear the patrons talking about KE as if it is the paragon of all virtues. WhileKE is a wonderful thing to be sure, it is not the only thing. Leastwe forget our old,often forgotten friend -momentum!
