Got great advice the other day on how many butts I would need for 30 folks. It's now 35 so I think the four 8 pounders will be plenty. Last question..maybe....I always use my vrack and drip pan for individual butts but obvioulsly can't do that with four of them. I have an XL with a plate setter. Will it work to make a drip pan out of foil to sit on the plate setter and just place the butts on the grate?
