I've tried a bunch of different ones. The Charcoal I liked best was the Weber briquets, but they are no longer available. I now use B&B briquets as they are about as close as I've found.
The door on my Smokey Mountain leaks like mad. When I first got the unit, Weber replaced it and it still leaks, I've tried with poor results to bend the door. I guess my next step is to get the gaskets, but I'd like to hear how others have solved the problem. Thanks.
