Im in a huge debate on either the weber 18 1/2" or the 22 1/2" and im undecided which to order on amazon. I see pros and cons but i think i can still smoke my butts on the two racks in the 18 1/2". PLEASE HELP, lol... I will order tonight one for my big BBQ party next weekend. Im unsure in using the 18 1/2" for spare ribs but i havent done ribs yet or brisket which i plan to soon.
