I recently picked up a bargain Cast Iron dutch oven from Calphalon. ($129 for $29).
All the cast iron I've used in the past were smooth inside. This one is fairly rough inside.
I've been continuing to season it and also for now cooking only fatty things in it, but I'm wondering if smoother would be more non-stick, or rough. Should I ask my husband to grind it smooth, or keep it with the rough, pitted surface for better non-stick performance.
Which would be more non-stick?

I'm getting contradictory opinions.
