Thanks all. I didn't want to ruffle any feathers but from a newbie ( this is my second brisket) I thought I'd reach out for some experienced advice.
I'm not going to cut the wires and inject anything in my rear but I think I will try the probe for the feel of butter. I could really twist that last line butt.... Lol.
I guess as a newbie a temperature indication is/was my crutch. I was under the impression that temperature would at least tell me about when to probe for the butter feel. If all fails I'm sure I can get some pizzas delivered.
