Matt, I understand what you're saying, and to a point i agree. I believe that the larger cutting DIAMETER will reach out and hit something you would have missed otherwise, say an artery. BUT, IMO the larger cutting surface would benefit as well. Simply put, more cut = more blood.

But, as is the case w/ nearly 100% of the archery industry, it's all personal preferance, and one's school of thought. There's just no question any well placed head is gonna kill a deer.....the heads I shot last year didn't have that large of a CD, but it's a 4 blade, and it honestly looked like someone took a 1 1/8" drill bit and drilled a solid hole through that deer. That thing bled like a stuck hog....
