RE: carbonwood vapor arrows, are these.......
Arrow weight is borderline, in my opinion. Not for penetration--if the arrow is flying straight and has a sharp broadhead, it should blow through any whitetail on the planet--but it will noisier than a heavier arrow, and might be a little hard on the bow.
I've seen umpteen ways to weight carbon arrows, but I don't shoot carbon and have never weighted one, so I can't say what works and what doesn't--sorry.
