As for the Jango 2-piece, color me shocked. I was at a guy's house trying to help him with his gear to get into the Legion and he pulled one of these out.
The plastic is more rigid than the vinyl 1 piece but a little lighter. The lines were crisper than I would have expected.
Overall, if I were a smaller guy and needed a starter helmet, this would be a decent base. Add a little bondo and you're good to go.
