This guy has done some pretty in-depth penetration testing of many types of broad heads. I haven't broke the code on all of it but it is still fun to watch. It is in three videos so it will take a bit to watch them all. He said more was to come but I guess he hasn't got around to it yet. Bummer.

Sorry Sonny, no broadband for you. Just keep doing what you are doing, it's working good.
