Well I decided not to cube and just let them go.
I pulled the first one at about 11hrs in. I should have known better. I've done many of these but this one was stubborn as ****. Pulled it at around 200*. Probe went in like butter fork twisted with ease.. She rested for about 1 1/2 hrs then I pulled. The outside was wonderful, unfortunatly the further I went in the less rendering there was. Needless to say that part got chopped. It's cool though I usually chop some anyway to mix with the pulled. The second one is still going. Just reached 200* 13hrs in. She feels the same as the first, so I'm gonna let it go a little longer.
