While I've never used a SM160, I used to use a CS150 before moving up to a FEC100. If this is your first Cookshack smoker, you'll love it.
As for tips in general, stay within the recommended suggestions for wood use. You don't need a lot to attain great flavor profiles. Cover the top of the wood pan with aluminum foil, as well as the bottom of the cabinet for easier clean up. Don't forget to poke a hole in the foil for grease access to the under pan.
