I think that the Bicep and shoulder bell overlap concept is great for people with long slender arms
but what about===
if you have short arms?
if you look at this photo in the back row you can see
a trooper with short biceps which requires an overlap.
---------------
look in the back row, we have a short bicep trooper, and in the front row we have a
longer arm at the bicep.
the bicep overlap will entirely depend upon the length of the upper arm.
there is not really much a trooper can do to change this unless they
use a non screen accurate way of shortening the bicep armor, which I think
would take away from the look, more than it adds.
