Mojobricks BAR-B-QUBES advice

I have never used these and won some in the BBQ Santa giveaway. I plan to smoke a pork butt on my OTG tomorrow for tomorrow night. I will be using the snake method. Should I use these like I would wood chunks or are they different because they are a blend/compressed. Directions say to place them beside the coals and let smolder, move if ignite. The ones I have are the Competition Blend. We have tons of food cooking and the Butt is just an extra. I plan to rub it with the Big Butz Pig Pollen. Thanks in advance for your input. FYI, I usually just chip some small pieces of pecan off some splits and place every few inches on top of the snake.

Thanks for the advice. I ended up putting them on top of the snake like I wood wood chunks. Came out great. I only have pics at start, 2 hours when I flipped, and 4 hours before wrapping at 165IT. Came out fantastic. Just was to busy with guests to get any more pics. The Pig Pollen ingredients are very close to my own rub I make. Very satisfied with it. Will use again.

LOL!:shock:
