You will be not be TGM compliant, which requires the left arm to be inert.
I had not really put together how "inert" inert means. Very interesting. So then if the hands are active that is one thing and they must be to control the various hinges, aim-points pulls or pushes. So then it is hands controlling the pivot.
Very useful. Thanks!
