I'm using the ITM Millenium and like it so far. It recently replaced my old ITM BigOpen stem. I also considered the Easton EA-70. Easton has a bit to say about their faceplate design and how it more adequately distributes load and stresses. The ITM faceplate design is similar in that it's shaped in a way to more intelligently spread out the load. Easton designed their faceplate with particular attention to their CF bars by taking into account CF's ability to dissipate loads in a certain fashion so you might say they produced mated component designs. However, I see no reason that wouldn't be beneficial for other bars unless of course your bars require a high degree of localised loading to keep from slipping.
