Well, I saw Demolisher today, and he didn't look as bad color wise as I thought. And because you both like him, I picked him. He's not bad, pretty good actually. His arms are too small though. Hypermode is cool, and he's got great articulation.
Went to a Wal-Mart and found the rest of wave three, that being Arcee, Insecticon and Mirage. I pretty much agree with you on the basics, so I won't say anything more.
Mirage is pretty good. He seems a bit loose, but he's got great articulation. The shell is removable of course, but I prefer to just have it stick straight up in bot mode. His hyper mode is kinda blah. I like the launchers on his arms though, and the minicon ports are nice bonus.
