I am smoking 2 racks of baby backs and 1 rack of spares tomorrow. Anybody have any thoughts or suggestions about cooking these at the same time? I just got my AMNPS in the mail yesterday and did a test run with it last night. I now understand the TBS concept. I have a MES 30, and before when using the chips in the tray, I would get heavy white smoke. Also this time I am going to try sand instead of water in the pan. During my last smoke I had a condensation problem. I have read on here where other guys have had luck with the sand so I thought I would give it a try. Any tips would be great.
