I'll be honest, I've never bought one of this mold and I don't plan to. The IDW Optimus wasn't my thing and Huffer and Pipes are pretty lazy and not G1 enough for me to use them as filler in my display.

That said, given that, besides some 3P stuff, my display is mostly MPs (with a notable exception for Takara Legends Arcee), I suppose that's not saying much, although I do own a tonne of CW things (Prime, all the Combiners/limbs and a heap of the Legends - Powerglide nearly made it in as a MP stand in, but I decided to use him with Superion's gun to match the G2 team).
