Don,
You flatter me! And it's not necessary. Although, really cool mods seem to gather nick names around these parts; Piedmont Pan, Minion Method, WSM Magnum, etc... Hoop and Caster Mod just seemed to fit your nicely done design. (A design I would use myself, except my twins are on a table about 16" high and I don't need to move them).
Without knowing the proportions of your rub, it looks like a good mix.
I have a green ham, approx 18-20 lbs that I am going to cut in half and put it on the smoker tonight after church. Hopefully it will be done before church tomorrow. 16 hours. might be.
Happy Easter to all the folks here.
