Hi All, just got a WSM 47cm (18.5"). 
First cook, only spread enough briquettes to cover the grate, and filled the bowl with cold water. Couldn't get my WSM up to temperature and had to add more fuel. Second cook, filled the grate to the rim, and put hot water in the bowl, and the temperature went off the scale. So guess I need to go somewhere in between. Read up here on this forum, so got some tips and invested in a Maverick 733. The meat I cooked, brisket and pork shoulder weren't too bad actually, perhaps a bit dry.
Doing some more trial runs, before a family get together in a few weeks time, no pressure
