The smaller y-wing mold has some good merits. It's about scout-sized, and while it lacks bicep or thigh swivels, it can still pull off good poses, and it's not a shellformer!
I remember when I bought it, I couldn't put it down; the transformation is both fun and intuitive.
Sadly, Seibertron doesn't have a gallery of it, so here's a picture! (I just realized I don't have any of my own, I should fix that!)
Thanks to those wrist swivels he can actually pull off a two-handed swing, it looks pretty good!
