If it makes you feel any better, I cooked my first rack of ribs on my 22" Kettle last Sunday and had less-than-satisfying results considering the care and attention I put into it...
Put them on at noon, kettle holding steady between 220-250°F, let them smoke for 3hrs, then tinfoil wrapped for another 3 hrs, then back in with some sauce for another 3hrs. After all of that, no love. "these are not the ribs we are looking for"
