Welcome Musepic pleasure to meet you. LOL..... The word for that problem with the Brisket is Patience. A wise Guru around here someplace will reiterate if you seem to forget.
Its a great board, its has great folks and the knowledge flows...... Most smokers, grillers, and BBQer's hold all there secrets close. I don't think there is any secrets here. FYI the search engine is bustin at the seams full of great info, just ask and ye shall receive, and its gets pretty dang specific if you do.
They easiest way to be able to duplicate, is notes. The best way to make it better if knowing what you did last time. You want to do a tweak, write it down so you'll remember what you had before and why you want to change something. If you have time come and ask for a Guru's help. Did I mention they are totally amazing?
Well if I can help, just ask, but I recommend the Guru's help.
Enjoy your stay, enjoy the smoke.
