So since you found some Muzzy failures, are you telling us that you beleive that a mech., the one of your choice, would've blown through the animal and stuck in the ground 10" with the shortest tracking job ever, if used in the same instances?
A bent or broken COC broadhead means direct hit on bone. NO? Are you telling us that mechanicals would've been the better choice?
If you want to play the " I found broadhead failure discussions on the net", then by all means, let's play. I'll bet I can find more mech. failure storys then you can find COC failure storys.
