Not this Midwesterner - I like my ribs closer to competition style - with some bite left in them. Plus, I'm a dry rub guy - no sauce. So, I'm not a fan of 3-2-1 either. YMMV
Doc did an experiment that I tried once, it works, just not my style, but maybe more up your alley. He started out putting them in the pressure cooker and then onto the KK. Cut the cooking time in half and it was really hard to tell they started out in the pressure cooker. You'd have thought that they we just done straight-up on the KK. Dennis played around with doing them sous vide, as well.
