That's a pretty good video. I agree with a lot he had to say.
Hickory is definitely my favorite wood. Miss Linda on the other hand, says it's too strong. She prefers pecan--same flavor profile, but milder.
Oak, I find kinda bland. Apple, I just don't like.
Orange is my go to wood for anything pork. That said, the best pork loin I ever bbq'd was with 60/40 mix of pecan and mesquite.
Alder is great for fish, but I find that willow is just as good.
