Yeah, the only major variations on the fiberglass version I can see is that the angle on the mesh stripe is less pronounced and slightly thinner, the chin is a bit higher, the temple area is less angled and doesn't flare out as much, and the inset line running across the brow and between the two ends of the neck stripe is not as prominent. jimmiroquai's take on the helmet shares more in common with the ABS version than the fiberglass, so I think I'll stick with the Anovos head when I submit for approval
