I'd be interested in a breakdown of your process
I used white oak to cook over (which I got last year)
Marinade in Montreal wine/vinegar for about a dozen hours
Fully lit about a half dozen charcoal (red hot)
added the wood which flamed up right away
Got the fire going pretty good and added the TT (the taters had a 30 minute head start on the gasser)
The total cook time was maybe 30 minutes for the TT, I had to turn it often to avoid burning it. If I had to guess, about every 5 minutes max
I controlled the heat by adding the door when it was too hot, and took the door off when it cooled too much but for the most part, I was probably cooking at 600+
Thanks everyone

This was a medium rare TT (I had been normally doing medium) I think I'm back to medium rare, it's definitely better
The best thing about this.....it was only $3.50 a LBS (about half of normal)
