I absolutely love Energon Grimlock, and think he fits in with the Classics line better than Classics Grimlock. I only have two very small gripes with the figure. First, the T-rex mouth doesn't open as wide as looks like it could. If you have any suggestions to amend this I'd really appreciate it. Second, and the main reason why I'm making this post, is that E. Grimlock's outward/sidekicking articulation (what, it's the best way I could describe it!) is very, very limited. If I dremel out the portion of the leg I highlighted in red, would that help increase the leg articulation?
