That is a really good point Rich, in that case our bells need to be more pinched at the top...
Anyway sorry for the slightly OT.
I think Mark has done a full strapping system, will let him chime in.
Another point to bear in mind is that if John B's suit above was made at the time of ESB (as per theory on SWHelmets), it may have a different strapping system to the actual ROTJ suits.
