Wow. Definitely would not go for "aged" pork of any kind.
Also, Duroc pork is about as premium as anything in a WalMart freezer case. I have to hand it to them for the marketing effort, but if you're paying any premium for Duroc, you got took. The only real premium pork breeds that are a Wagyu level are Berkshire/Kurobota and Swabian Hall.
