Hi. Tomorrow is my first run on an 18.5 WSM. I'm smoking baby backs. I'll use both grates. I've always soaked my wood when smoking on my kettle grill. Should I with this smoker? Second, I usually use the 3-2-1 method. Is that still a good idea? If so, do you just pull the top grate and set it aside while you do the wrapping? Thanks for any help!
