Okay I have been studying these in detail versus the screen shots and other images posted in the gallery (http://www.thedentedhelmet.com/gallery/showfull.php?photo=11164 specifically) and the cape looks like it was modified from what it's original intent was. When / how is the best way to attach the cape just to the corner shoulder?
The original Supertrooper had no cape (the Star Wars towel was added after GL decided to convert it to Boba Fett):
The Pre-Pro #1 had one end of the cape attached to a clip mounted on the jetpack and the other end to a clip attached to the right side of the collar:
The Pre-Pro #2 seems to have the cape inserted somewhere between the inner part of the collar/back plate attachment:
The Pre-Pro #3 had the cape attached to the clip mounted to the jetpack (same jetpack as the Pre-Pro #1 minus the rocket):
The ESB hero had a different cape (new design) attached to the outer left collar stud at an approximated 190-200mm distance, while the end of the cape was squeezed/attached to the upper left jetpack hook:
It seems that the ROTJ (and the SE versions) is the only suit that had the cape attached that way (end of cape under the outer left collar stud):
