JM, hope you're getting kickbacks... this officially convinced me to go down to Lowe's and pick one up over the WSM. Of course, egg would be fantastic, but at 1/3 the price, this is impossible to pass up.
Echoing the above, I'd like to see a 225 sustained. Maybe use some good ol cheap kingsford charcoal, and see if that helps tame the beast? You're really ratcheting the airflow to almost nothing, and it's still looking like you can't get it down there.
Awesome stuff man. Keep those videos comin!
