Accidental testing is often the best. One of the reason's we never accept lab testing alone when approving a head.
I had an early prototype of the Ti-Con that passed every single lab test I could think of. Zero failures and some quick kills right out of the gate. But got it into the hands of a few other field guys and we quickly found a flaw in the durability of the ferrule. Luckily accidental testing was successful in showing us the weakness before we brought it to market.
One of the reasons Justin Llanes is so important to our success. It's not necessarily all the goats, pigs, and sheep he shoots, but the punishment all that big island lava rock puts on a ferrule. Just can't duplicate that in the lab
