I like lean brisket Hickory or Pecan flavored; bbq or smoked. Spicy sausage, too. As long as it's Texas-style.
If it's served with sweet BBQ sauce, or, white potato salad (mayonnaise / Miracle Whip), or Boston baked beans, then it's NOT Texas-style regardless of technique.
Permian Basin is pecan country! Pecan is great.
Fruit wood for pork.
