Ok, I've done 3 cooks on the 22 WSM. Nothing in the pan, just foiled. What I've noticed is that after 3 hours at 225F, temps steadily climb to 250 to 260 after that. I'm assuming it's because that their is no heat sink in the pan. Also, the cold meat has come up to temperature as well. Ok, I really don't want to use water. So I may go with the sand method. Will sand really help as a heat sink? Also, whats the proper way to put sand in the pan? Foil bottom, put sand directly in the pan, foil on top of sand? Other than this minor issue, I've got this baby dialed in.

Hi Luis...I use sand exclussively, I don't trust myself around water. But here's what I noticed with my 18.5 WSM.
First, unlike water, sand is not cooling temps....it absorbs temps. Water cools temps. That means, when using water, the temps drop, which promts the fire to burn more intensely, which in turn raises temps. With water there is always a better chance to run out of fuel, although the firebox is big enough to hold temps for a very long time.
Sand on the other hand has the opposite effect. Sand absorbs temps, which keeps the fire burning with less intensity, cause it doesn't have to make up the difference....hence lower, and more importantly, steadier temps at the grate level. If you use sand, better if you put a chimney of lit coals first, then cover them with unlit coals...you will notice the temps are increasing much slower than the other way around.
When foiling up the water pan, the bottom side goes first, then the inside and after that, add sand about 3/4 of the pan, then foil the top inside of the pan twice....once for the sand, & the other time for the drippings. It is recomended to leave a bit of air between the 2 top layers of foil, that way the dripping wont start burning.
