Watch this video on how he does them. Looks pretty good, but id only get 1 rack on a 22in weber kettle?Ah.... now I'm up to speed.....
babybacks will work very nicely for you.... Smoke them for 2-3 hours wrap them in double layer of foil, then in the cooler with towels. Got to the location.....get the charcoal hot for grilling, finish grill on the charcoal and glaze with sauce of choosing! If you only smoked for 2 then just grill a few mins more.
I use to do babybacks hot and fast on the grill all the time, ie babybacks are perfect for hot and fast. But the 2-3 hour smoke then finish will produce a very nice rib....I will note the it may be easier to 1/2 the racks when grilling but thats your choice. I would cut them in 4 rib sections the smoke then finish grill on sight.
Iv done ribs many years ago on a grill at 350 . Thay where ok but not great .
That was when I was first starting to grill . Iv been afraid to cut the rack up thought it would mess up the way thay cook
