Since I use fire to smoke meats, there is no way I would use plastic wrap on any of my meat while cooking, especially if you have a low end smoker where there is a tendency for spikes in temps during the cooking process. I saw the team that used plastic as well, but I am always cautious about using a technique that isn't common. Additionally, it seems like that team may have used a pellet smoker (cannot remember) Yes, that team may win comps, but we don't know what steps might have been omitted when the filming took place. IMHO
