I just got a replacement AB/Cod piece from AP for me, so I'll be updating my armor, then see if I switch my chest plate with Greg's chest plate... if that helps his chest choking issues.
I actually haven't compared the two chest pieces, yet.. but I'm hoping the AP chest is not as round as the RTMod. I'll post pics when I get that done. For Greg's rotj Vader build we
have shin and shoulder armor, and ordered most everything except the helmet and cape... but are working on those. Fun stuff!
