Actually mine came in today! I never got a shipping notice! Russellsch, my helmet was right next to yours, #36! Overall I'm pleased with it but the thing is completely covered with speckling as mentioned before, which doesn't look great to my eye. It'd be tempting to tone it down a bit but I dunno if I'll bother.
Looking at the RS/EFX comparison pics above, it does appear the EFX is smaller (mine doesn't even come close to fitting on my melon lol) and it's interesting to see the visual differences. I prefer the glossier look of the EFX and on the faceplate, I notice the nose "bridge" area looks wider. Also appears the visor is larger with more surface area?
I'm glad this 9yr journey is finally over. While I'm iffy on the weathering and it sucks these things weren't built true to the originals, between this and the "free" PCR Vader we got, I'm pleased overall and glad to close this chapter. It's a fine looking helmet. However, if I ever buy another EFX product, it'll certainly be secondhand or from a distributor!
