Jordan the only reason i do spritz my ribs is to control the bark, once the bark gets the color i like i start spritzing usually after the 2-2.5 hr mark for BB and 3-3.5 hr mark for spares, good luck. Spritzing adds no extra flavor to the ribs imo. I use 50/50 vegetable oil and apple juice for the spritz. Make sure you shake the bottle before each spritz.
