I have no doubt any of the new broadheads, on the market, work. The manufacturers have to spend too much time checking on the efficiency before they sell them to the general market.
Both bloodrunner and rage seem effective. A little more engineering, more marginal effectiveness and good appeal to the newbie archers.

I'd only warn a newbie to check the working of each arrow broadhead before they hunt. It's not uncommon, for individuals, to foul up the operation of a mechanical tool-even a mechanical broadhead.

The problem really comes from newbie hunters with little experience, who needs the added confidence in a more effective tool. Good shooters make good harvests. It often comes down to practice, training and confidence, which effective broadhead the archer uses. Or can still obtain. Markets do change rapidly in archery. Sometimes the only reason I study them.
