Basically, I like Energon Grimlock. I wanna like Classics Grimlock, but really have issues with the wonky shoulder joints, tail, and forearms. I love the classics head sculpt though, which led to this thingy. My intent was just to test out how it looked, but things got to a point of no return rather quickly. I'm reasonably pleased with the look of the Classics head on the Energon body, and happy to report that it still transforms fine (I was worried it wouldn't fit in the space the squatter Energon head did). I still need to do some work yet, as the E. Head on the Classics body is held on with little more than tape and wishful thinking.
