I'm new to smoking and bought a used Masterbuilt M7P that needed a new waterpan. My question is it what to replace it with, do I replace it with the same matierial pan, or stainless steel water pan? Is there any recomendations? It is a 15" pan coated pan that is in there now. Don't know if Stainless will cause any change in the flavor of what is being smoked or not.
