Has anyone else noticed that the Smokeware cap seems to make it much easier to stabilize the temp of their Egg? I am referring primarily to the 350-375° range where most of my cooks are done. With the DFMT I would often have run away temps after it seemed to be steady at a set point for an hour or more only to find it at a considerably higher temp later in the cook. This has happened on both my M and my XL. FWIW, Both of my caps are of the "looser" variety but seem to maintain set points quite well.
