Sounds like a plan. If this is your first one, like you say in your post, remember a few things. It may stall on you, don't panic. If you drink beer, now is a good time to have one or 2
. Just ride the stall out.
I don't know what temp you plan on pulling it out of the smoker at, but for slicing, I would go for 175-180. Wrap it up good in a few layers of foil, a towel around that if you can and into a cooler so it can rest for at least 30 minutes, more if you can. It will still continue to cook when its in there a few degrees.
Oh yeah, don't forget to take some pics for us. And of course, any problems come up or you have questions during the smoke, you know you can always come here and someone will help you out. Good luck with it, I know it will turn out great
