RE: Speed or Weight for maximun KE?
When looking at the KE of a particular setup, the change will be negligable when shooting different weight arrows. Where the heavier arrow has an advantage is in momentum, the biggest component of penetration. But again, I don't feel the difference is that great at normal hunting distances.
