Regardless of height or central apex creases, which can vary a bit:
--one cuirass shape appears to be fairly uniform globosity from side-to-front-to-side

Its almost as if approximately between the sides and center this alternative cuirass flattens just a bit, allowing the profile peak to rise upward a bit. Im not suggesting a wasp or even greyhound look, as the shape would not be terribly different if viewing it from the front. Only the side profile or a 3/4 angle would begin to show a slight difference. Ive been wondering if its just me (always a possibility
Off hand I cant think of any specific effigies or extant examples but I thought Id kick off a discussion, see what you all think.
