Congrats, looking forward to the rib report.
Cooking temps. There will always be controversy about what temps.
I say try it and go for what works for you.
For me, sliceable is between 180 and 190
I never pull below 195.
But there are always disclaimers if you want to be precise. The outer portion will always pull easy at the lower range, but notice the inside. The big musles will not pull apart easy. That's why most shoot for 195 to get all the meat to pull easy, including the big muscles.
Just keep notes and follow them for a couple of cooks and you'll improve your own methods. Shoot, what do WE know about your cooking, I've never tasted it
