Yeah, they're really nice sculpts. A tremendous amount of detail packed into each mini.
I had several packs of the new vistula legion I parted with, in part because of some things you touched on in your review. The metal is extremely hard, like you said, you can't clean it up with a knife. I had to use my side cutters just to clip the vent lines off the bases in many cases. In addition, the metal seems brittle. I had three pieces that arrived broken off at the ankles, where in other minis, they would have simply bent.
The scale put me off a bit; they (the new vistua legion, at least) are even a little smaller to my eye than newer GZG sculpts. That said, they probably scale very nicely with Peter Pig's line.
