Just responded to your PM, but here in the forum is better, so we can share the help:
Wood matters for SR. I love Cherry, but use what you have. For your first one go with 180 for 4 hours, then bump the temp to 250.
If you have an IQ, you can do this simple.
Set time at 4 hours, put temp at 180. Set hold temp at 250.
When it hits 4 hours, it will "hold" at 250. Lots of comp people do that.
As it's your first cook, I would watch it,to make sure it does fine.
Put it in either of the two middle shelves, fat DOWN and just move it at one point sometime during the smoke (fat tends to sink into the shelve then the brisket sticks. Just move it from that spot so it unsticks.
yes, fat down.
