AnakiMana,
I started with the 22" WSM too but found it was just too big for my needs. It's a real monster. A big beautiful monster, but a monster non-the-less. I sold it to get my 26" OTG, which I love. I really do love the 14" WSM because it's so efficient on charcoal. Admittedly it sometimes falls short on space. I think between the 14" and 18" WSMs, my needs are covered.
