Sounds good, Jim! One thing a lot of us do is actually weigh our wood. It can be deceiving, sometimes. I actually tried to figure out the dowels, and came up with .64 oz per inch (this could vary slightly, depending on the density). So, about 4" total would have been plenty. I use 2.5-3 oz on ribs, and it's perfect for my crew.
Lots of good rubs in the recipes sections here. One of my favorite "store bought" rubs for pork is Famous Dave's Rib Rub. I know, cooler to make your own, but this stuff is easy and pretty darn tasty. Give it a try sometime, if you haven't.
I look forward to your future successes! Maybe this winter will end someday, and everyone will be smoking more! Way to go hardcore in a blizzard!
