The vast majority of my collection is C/H/U/G, with a couple of exceptions - G1 Jetfire, ROTF Bludgeon, and Faith Leader, all of which I think "work" with the rest of the group. I've been reading one of the photocomics on here and am enamored with Alternators Shockwave . . . but I'm guessing that the scale would be kind of screwy. That's not a huge deal because I'll probably keep him in 'bot mode. I'm also kind of interested in Cybertron Metroplex . . . but I'm not sure if those will coordinate well with what I've got thus far. In your opinion which figures go well with one another across different toy lines? Do you use movie figs like Gears and Brawn to stand-in for their G1 counterparts, or no?
