I actually was planning to review Chromedome on my own, but Quinncat over at CollectionDX had one that covered all the bases.
My additional observations:
The IDW head really is the icing on the cake, and will probably make you want to get the new rewind figure to make up the Conjunx Endura pairing. Other than that, I love how the colors of chromedome in figure form gives it a Diaclone vibe. Sadly, the cockpit size of teh headmaster makes for a really big Seat, if you use the Dia-Nauts. It works if you think, as a friend said, that the Headmasters are over-sized extended power suits for the Dia-Nauts (thus marrying the two lines neatly, in headcanon).
