Thanks! Was a little smokier than I prefer but was a hit with everyone else. I like a milder smoke....still dialing in the technique on the WSM...
This is the Mac n cheese recipe I used. Very easy and very awesome.

Used apple, oak and pecan. Everyone loved it and the leftovers were a hit, I think if I just hold back a piece or two of wood it will be in the sweet spot for my taste...
