Use a Rocket Hamerhead 2" 3 blade, Rage 2" 2 blade or any mechanical with a 2 inch or bigger cut and those not so perfect shots won't be so bad anymore. You will find more wounded deer with broadhead that does massive damage over your traditional 1" or 1 1/8" fixed blades.
Plug a brute in the shoulder with your massive rage BH and see if you still have that opinion. Cutting diameter can help with 'soft' tissue hits tho, I agree.
its no substitute for hitting where you aim though. (I am NOT implying that you were saying that)
