When we had a hog roast a couple of years ago they came in in the small hours of the night - 2-3 am ish and lit up the gas thingy, and it spit roast for something like 14 -15 hours. Heck of a long time anyway. We are having another in early August, so the litter born at the end of Feb will be just over 5 months, so a couple of them should be likely candidates! (They are GOS cross large black) I'll walk them all through the weighing crate near the time and select the best!
