Both sets of ribs look awesome...Give grilling the ribs a try on your WSM you will not be disappointed, just remove the water pan, fill your charcoal basket about 1/3 full with unlit charcoal, light 1 full chimney and pour lit coals over unlit coals. Start grilling your ribs, in about 2-2.5hrs...
Great looking meal, beef cheek tacos are awesome, beef cheek meat is the only true (barbacoa), you can use any beef meat and braise it and call it barbacoa but its not. Tip try some re-fried beans with barbacoa in a taco, you will be in heaven.
Take the sticker off of the knob, under the sticker there is a phillips head screw. You can turn the screw clockwise to give you more power. Good luck!
Jason, I would allow a minimum of 24 hrs for a brisket that size at 275. If it finishes early you can hold in a cooler for a good 5 hrs if need be. At 225 you are looking at 24+ hr cook. Good luck.
