Your right the Digi II/raptor will give you the same control as a PID does. I don't know if there would be any effect on the ability to heat the cabinet though. I will say that I really do like the fact that I can maintain a more accurate temp for things like jerky & sausage etc. I don't think the DBS temp swings really hurt anything when you are doing ribs, butts, etc. but I do prefer to have the ability to control it a little tighter.
