Ok, so basically the dome is too round, and using the batting helmet cut in quarters and put back together with bondo is the best way to take this?
More expensive than I was hoping (I shouldn't complain, it's only $12, and the paint was going to be a decent investment anyway), but still cheaper than buying a GMH. 
I think the GMH will be my first upgrade, when I can afford it. That is one of the most beautiful man-made things I have ever seen.
It may be worth noting, but I'm going for ROTJ with my costume design scheme. Are there any notable differences in the helmet shape? I know about the rangefinder differences and the paint differences...but anything else I ought to know about? I've read through so much material that any such details have gotten lost in the huge tangle of information I'm now holding in my short-term memory.
The one thing that gets me about the ROTJ is the helmet colours. I like the helmet colours from ESB best (mostly the yellow kill stripes, the scratch/weathering details on the ROTJ are nicer), but the armour detail and the mandalorian insignias from ROTJ are more pleasing, IMO.
