So, I recently got a Pilot, and as I'm getting used to operating it, I finally figured out why it was putting a lot of strain on my lower back muscles.
I have a somewhat protruding but muscular upper abdomen combined with a sunken chest, which puts the vest center bar and arm mount at a backwards angle when I stand with the rig weight balanced over my center of gravity. Standing so the lower pivot point is perpendicular to the ground and the arm swings freely involves leaning forward, which involves a bit of back strain.
So, is there a kit or something available to make the fore/aft arm mount angle more adjustable than the small amount afforded in the thumbscrews in the mount itself? I'd like to figure out how to use this thing for longer periods without worrying about muscle exhaustion.
