Just wondering how much wood you all use? I have the cast iron pan on top of the original chip tray and use a fist size chunk of wood or the equivalent amount of smaller chunks or chips. Basically a handful of whatever kind of wood I have. I prefer the fist size chunks because one can give almost two hours of smoke. I do this the whole cook. So basically I fall in the light/medium smoke for the whole time camp. I notice some people using 3 or 4 fist sized chunks at once so I am curious how long it smokes before replacing and does te food taste really smokey. I tend to get a lot of white billowing smoke when I had more than my normal handful. Thanks!
