I utilized a "modified" 2-2-1 on a couple fatties last weekend, and they were awesome. I lowered the first time increment from 3 hrs to 2 hrs cuz 3 seemed a bit long to me considering I previously cooked 3 hrs TOTAL (no foiling). Now, with 2 hrs foiled, 2 hrs naked seemed plenty. And it certainly was. I followed Bill's advice and heavily "juiced" 'em before foiling. I even managed to cooler them for very close to the full hour before I finally caved and opened one. Best ever.
Because of 2-fer-1 sale, I went with Owens brand - no complaints.
