2 6lbs Pork Shoulders = 1 12lbs shoulder in Cooking Time?

Unknown

I have two pork shoulders weighing in at about 6 lbs apiece. I am plan on cooking them at the same time using the recipe on the Naked Whiz's website. As for cooking time, should I base it on the fact the each shoulder is 6lbs - therefore about 12 hours (at 2 hours a pound)? Or, should I plan for it to take as long as a 12 lbs - therefore about 24 hours (at 2 hours a pound)?
Thanks for the help. Got the full family in town this weekend and want to show them what the Egg can do!

As long as the two pieces of meat are separate, it's like cooking one piece of meat. If you tie them together with a bunch of string, then you got one 12 pound piece of meat and it would take longer. [p]TNW

Double Deuce,[p]I cooked two 5 lb'ers (boneless) last weekend and it took 18.5 hours at 225 the whole... to internal temp of 200. Just in case plan for a longer cook and keep em in a cooler untill dinner time![p]Brian
