Sort of, kind of.[8D] It all started with our mutual Bowtech dealer telling him he could outpenetrate any and all heavier arrows with those arrows simply because of the speed he would be shooting at. I know the dealer is pushing him to buy some of those arrows but he kept mouthing off about being able to get deeper penetration on the basis of having the lightest fastest arrow, of which the dealer is telling him. I won't argue with our dealer....he is a good guy and does great work on bows, installing string loops, peeps, etc. He hasn't picked the bow up yet, maybe this weekend.
