The TTBP looks like it might be good too, but it's hard to tell from these pictures.
I wish they tossed out the mech and just put more effort into the VAMP.
The Moccasin is cool, but I wish it were green. I'll have to get and extra one of those sets to lengthen it and add in a gunners seat.
I like the Dragonfly well enough (though there is room for improvement), and I'll probably be army building the Ninja Dojo set.
