Yaay! I helped!
I also talked to my local butcher, he said he'd order some 50/50 pork for me. Should be here this thursday. He said that's what the deer proce$$ors use.
We spoke briefly about a broad spectrum of fat, so I kinda forgot what exactly I'm getting... I think it's pork belly. When he brought up pork belly I asked him if it was un-cured. Hopefully I'll get to talk to him a bit more in detail about exactly what he's sold me.
I asked him about pork fatback. As I understand, that's the backstrap of fat on a pig, the filet mignon of fat. But he dismissed that option quickly... don't really know why. I'ma ask him again about it.
