I'm using a low-def model of the ODST helmet, and leaving out the detailed ridges. I've never seen 2 pepakura works come out exactly the same, and in the end, it's up to the builder to decide how he puts his props together, and what customizations he makes. However, it's a good strategy that works and can bring new people into the art. Sure, hardened pros don't like it, because they learned their own, harder methods.
