Pig orientation wouldn't matter. I've seen pigs fly in a W'ham (and I have the t-shirt!). My biggest question was on the diagonal, butt towards the firepot or towards the exhaust. Tail end down seems obvious (don't know why). Suckling pigs would hang well in an FE100. Doug posted an interesting sounding method over on the other forum. John Willingham hangs every meat in the carosel in his W'ham cooker.
