I used to lust for that DP so much. I think it still looks great. Interesting to see the gun metal cheer swapped to the other side. Also, I read somewhere that the higher numbered Vader DP's had bad neck flaring problems. The lower edition numbers didn't have that issue, because the molds they were pulled from were still on good shape. But the more helmets that were pulled from them, they started to sag.
Congrats on getting the eFX, I think they did an incredible job on theirs. Now you have a Vader helmet for both movies. Are you happy you got the eFX?
