Finished up the course and wanted to say thanks Jeff! Basic info but very important! Never did the 3-2-1 method, but giving it a try on a rack of spares right now. Ordered the rub & sauce even before the course, but still feel it was a deal. Rub is a hit and replaced what I had been doing. The sauce will get a little tweaking to suit my taste, but also keeping it in it's original form so friends have some choices. This whole site is an ongoing and ever changing resource - Thanks all!
