Butcher my own and make my own sausage. The ability to decide, on the spot, what to do with a particular cut is what I like the most. Since I'm feeding two people, I like to cut everything into 2-4lb roasts. That way, when I defrost, I can make a roast, cut into cubes for stew, slice thick steaks, thin steaks, etc. And we are not eating left-overs for the next 4 days.
From what I've heard around here, you'd be lucky to get your own deer back if you had it professionally cut.
