To light is not good for hunting ,when I have a bear or boar or a good sized deer for that matter I want an exit hole on the far side even if the animal is standing on a little more of an angle than I can tell or moves as I shoot. I took my 109th deer last year with a arrow [that’s not counting gun shot deer] and have been hunting with one kind of a bow or another for 60 years and tried about every thing, and the only time I have ever had a problem with how much penetration I got was with mec. Heads and with carbon arrows. The difference in trajectory for an arrow that is going close to 300fps between a 350gr arrow and a 430 gr arrow is very little but the difference in penetration capability is apparent. Lee
