Reporting back...
First run was a decent success. Had two 3 lb briskets from back home to smoke, rather than one 6 lb brisket as the instructions/recipe called for. So, I probably should've altered cook times just a bit but didn't.
One was very fatty and came out great... very moist and flavorful. The other, very lean, came out with a great flavor, however was a bit dry/tough although not so much that it still wasn't pretty good.
Installed a digital thermostat into my Traeger Junior before getting started and started them on "smoke" setting for 4 hours, then turned up to 250 for what was supposed to be another four hrs. However, they were at an internal temp of 200 within 2.5 hrs.... I'm guessing this was because there were two small briskets rather than one big one. Smoked them over a 50/50 pecan/mesquite pellet mixture.
Thinking about trying to do some ribs this weekend...
