You can't argue that a 3 blade with a smaller cutting diameter has more cutting surface because it's punching a hole in a more concentrated area.........a 2" cut single slice wound channel doesn't benefit from this.

I shoot mechanical heads personally for one reason..........OVERKILL. I can get wider lateral wound channels than I can get with fixed heads. I want to damage as much stuff as I can over as wide of an area. Penertation means very little to me because there really isn't a head made that I am going to have a problem with driving through deer sized game consistently and reliably.

Conversely I cringe when I hear guys shooting a head of a similar small cutting diameter but possess a bow set up that is providing them with ample energy to consistently use larger cutting diameter fixed or mechanical heads.

Use excess energy to your advantage.........the energy expended jamming a small fixed head through and into the dirt 10" can be better used by shooting something larger and more lethal through and only 6" into the dirt.

Understand your bow and what it can do to it's fullest, think about why things should or shouldn't work and make smart choices.
