That rub ended up with a great flavor to it. Will definitely be using again with beef! I tried the "cube it first" method of poor mans burnt ends the other day, and they weren't as good as the first that was smoked whole and then cubed to finish. While I did get a better smoke ring/bark all the way around, they dried out before getting tender. In part because it's a pretty lean chuck roast to begin with, and in part because it was a cheap Aldi cut and not the good stuff from Keener which has much better marbling/fat content despite being lean.
Last night I did a pair of BJ's pork loins char-siu style on there with some apple wood, and it was the juiciest, most tender pork I'd ever had. The only thing I'd have done differently would be a little heavier with the smoke up front, and ramp the temps up for the last few minutes to help crisp up that glaze on the outside, maybe even just finish off direct over the coals.
