We do raw for our 4 dogs and supplement with Evo red meat and canned tripe. They get the evo about once a week along with the tripe. I do it just in case I'm missing anything in the raw end of things, and there are days that I do training with my GSD where it's more convenient to feed them the Evo. I wouldn't want to feed it exclusively, it's way to expensive. But considering we go thru about 50lbs of raw meat a week, how much worse could it get.
