Hey Pete, those ribs look good for a first try. What kind of ribs were they? I prefer baby backs and use the 2-1 1/2-1/2 method of cooking and I usually cook at 190 to 200 pit temp. If I cook larger cuts of ribs, St. Louis style or back ribs, I will cook using the 3-2-1 method. Don't waste your time trying to make a rub. I've spent and lost thousands of dollars wasting time, spices and meat. Find a rub that you like and use it until the next rub that you like comes along. BBQ is not an exact science. Everybody has their idea of good and bad, right and wrong, and high temp or low temp. If it taste good then I will like your BBQ and so will everyone else. And by the way, you need to season that smoker a little more. Way to clean for me.
