Ya know, even though bad mouthing them is the thing to do these days, aluminum arrows really won't give you cooties.[8D]
I'd forgotten about the Grizzlystix. From the Alaska Bowhunting site: "BIG FIVE AND DANGEROUS GAME HUNTERS: By adding internal point weights and stronger and heavier broadheads, i.e. Silver Flames, a 900+ grains arrow with 25% FOC can be achieved."
Good call, Jim. Might be what he needs.
