Your average reader is gonna read that and think a 500gr arrow is "better" and is goingto carry more "momentum" than the 350gr (I'm OK using your examples) arrow he's now utilizing.
That is SERIOUSLY misleading.
Not if they have common sense.
If I have one bow, I can't shoot a 500 grain arrow the same speed as a 350 grain arrow with all things being equal.
Misleading to the ignorant yes, anybody with a brain, no.
