I have to give my experience with all things Lockhart. I’m sorry my experience didn’t match yours. Enough said.
My recipe for hickory smoked brisket:
Ingredients: room temp packer brisket, lots of iced cold beer, 1 large Weber kettle, real hardwood briquettes (not generic charcoal), hickory wood chunks (not mesquite), your own rub - don’t use a liquid starter or your meat will taste like gas, and your own sauce. Mine is vinegar heavy not sweet.
Use the “snake” technique, your grill vent, and your metal thermometer through the vent to keep the proper temp, HD grill foil for wrapping after the cook, and a clock.
I know what temperature and time including the after cook finishing/resting technique I use, but use your own preferences here. Cook it unwrapped except for the rest/finishing process which is essential.
Ribs are similar except on cook times and other nuances like prepping by removing membrane. Lots of YouTube’s on this.
