I am sure, by now, that it is no secret that I consider it to be inappropriate to use plywood, steel, tires, fruit, etc, as a medium to determine penetration capability and durability of broadheads.

Broadheads are designed to primarily penetrate wet and lubricous tissue and certain bone that is living and somewhat hollow. Most bone will often break or fracture when impacted by a broadhead; plywood, tires, and steel do not.

Although I have no personal disapproval of " 5 shot," and although I believe he is trying to be earnest when evaluating and comparing the performance and durability of broadheads, in my opinion the tests might be entertaining but that is all they (tests) are. I personally would not choose or reject a broadhead using such tests or scoring.
