I also just joined the forums, and have the Masterbuilt-30 digital. We took down a dead hickory tree last fall, so I thought if some smoke is good, isn't more smoke better?
My first smoke was 1.5 racks of baby back ribs. I ignored the you tube videos from masterbuilt and put in about two cups of hickory (over time). For us it was too much smoke.
Next up I did some chicken breasts and leg/thigh quarters. 1/2 cup hickory and a wonderful result. I'll look up the thermometer I used when I get home (currently on vacation). It has a much smaller probe than the Masterbuilt and has a remote so I can wander around while the meet cooks..
I expect YMMV. I am keeping a journal (old school, pen/paper) for now recording the meat, rubs, time/temp ....
Best of luck with your new smoker!
