I'm just curious, What will the MINUTE size difference make? What could you NOT kill due to the fact that this head is one tenth smaller than the old one? I looks stronger, straighter and more "arrow" dynamic. I would rather shoot a head like this, that will shoot straight and penetrate deep. 7/8" or 1 1/4" thought the lungs still equals a dead animal. Plus the narrow head has a better chance of shooting completely thru the animal. I believe that depth of the wound channel on alot of shots is more important than width. Of course I have only killed about 2 dozen bull elk with a bow and arrow.
If you look at the Grizzly heads they are not that wide after you grind and sharpen them, just over an inch, and they have one less blade!
Any way enough of my ranting, I really like the head!
