We are delighted to have a "big boy" at our event and have created a separate category (Unlimited air cannon) so the trebuchets will not compete against the air cannons. The rules will be exactly the same at the world championships's. I believe they require a 8 to 10 pound pumpkin, with no wadding allowed.
