I really don't think you can blame the broadhead fellas. You're looking for something simple to lay blame without considering all of the variables that go into the end result (e.g. shot placement and the vitals that are hit, hole plugging, deer behavior after shot, etc.).

IMO - There is no head that is the "best bleeder". For every head on the market you will find a handfull of people that love them and an equal amount that don't.
