Nobody answered my wood chip questions so I just winged it. Had the foil pouch in there at a high point of about 370 and it never smoked. Eventually the coals were in danger of cooling off, it was taking so goddamn long, so I took it off and just got my steak going. Not sure what I did wrong. I might have poked too many holes in the foil and the heat wasn't able to build up inside. The metal box they sell at ACE Hardware has plenty of holes in the top though. Maybe the foil pack was stuffed too much and needed more air space on the inside. I really don't know. Throwing them on the grills right before cooking doesn't do much except make them burst into flames, which I suppose does emit some smoke.
