I did some spare ribs this weekend on my 7 in 1. I did 4 half racks for three hours and then foiled them for 1 hour and then just opened the foil for the last about 45 mins. They were good and came right off the bone, but I had alot of pull back on a couple of the half racks, like almost an inch when I opened the foil. I did not think to take photos as I was really working to keep constant temps as we had more wind than forecasted. They were good, but I think that they could be better any suggestions? Should I switch the racks from bottom to top while they are foiled, do you think some of them maybe got a little too much heat and were overdone?
