Where/what type of fat for lard

[flikerstance]

i saw a few vids on how to render Lard it's very easy I love fried chicken and I have only ever had that cheap 2 dollar Goya brand lard from Walmart so I WANa try to make some real lard myself it should taste amazing but I'm wondering what cuts of pork would be best if I could use pork chop fat also and what I should ask butchers if I were to buy from them
