Man, I'm learning things left and right in this thread. Get some sort of Xacto with a grip, check. Start helmets from the top and work down, check. Fiberglass is lighter than rondo, check.
It's coming together really nice, and yes, you are crazy for enjoying those small pieces. Exactly the sort of thing that stopped me from ever getting my NCR Ranger mask off the ground. I'm working on an ODST BDU, so hopefully I won't have so much in the way of delicate little pieces like that.
Keep up the spectacular work, I can't wait to see it finished.
