Looks great. I usually cook mine at 225-250 to an internal of 125* and then let it rest a bit while I get the cooker up to 400* or hotter, then back on to get a crust, which doesn't take long. The difference for me is I cook mine boneless on the rotisserie, I'm not sure how the bone on will play out. Only cooking to IT of 115*, not sure that the meat at the bones would reach even a rare temp of 130*. I'm sure that many others here that have done the bone in will chime in and get you the info you need.
