One plate is out of alignment. :OTry using a static motor setup so you can get better wedges.
I like the design. The thing is, the way you've attached the weapons at the moment, they're going to bounce like . The plane of rotation of the weapons on a VS and the snapper they're mounted on should never match (I learned this in BTTB1). Try rotating the snappers 90 degrees, and try having them both on one SnapperII. I reckon you could get better wedges somewhere from that, maybe swap grannies for shinies?
So it'll turn faster, I imagine. And to reduce the likelihood of flanking.
