I have a Pitmaker BBQ safe, and an homemade offset comp trailer. I like the flavor of the offset better too. However, I sometimes put a few pieces of post oak, bark and all, in the charcoal box of the safe. I think it makes a big difference. The limbs of oak I use are about 2" in diameter, and about a foot long.
