I do babybacks on the UDS no-foil at 250-275 depending on where it settles. I start them bone down and flip at 90min and then back to bone down for the last hour.....they are usually done in less than 4 hours. If I take them close to 4 hours, they are often falling off the bone too much. They also get darker and I like the bark, so I hardly ever foil. I do spares the same way, they just take a bit longer.
