Congrats on the new WSM, you are really gonna like it. The first time, should be soft sweet and gentle
So, use some rub you like the taste of and cook them over some apple or cherry at about 225*-250*. Don't overdo the rub, let the smoke and meat shine through. Cook them until they probe tender and pass the bend test. No water in the pan and get ready to watch it puff for about 5 hours. Sit back relax, crack a beer and no peeking. good luck and let us know how they turn out.
