John, with the L bracket you do support the camera from underneath, as was pointed out in post # 21, if not sooner. If you use the L bracket as it is meant to be used, and as described in post #21, then there will be virtually no torque on the wrist. It's just like the vertical grip orientation that 35mm sports & wildlife shooters use and feels similar. Even if the right hand goes away for quite a while, it actually feels quite comfortable and stable (n.b. I am weak according to Tim, so if I can do it...) but in the worst case the camera simply rolls 90 degrees into a comfortable hang. I have walked around with the rb hanging like that and it's totally fine. No stress on the wrist.
Torque is definitely not on your side with a vertical pistol grip underneath: any instability, and the full weight torques the wrist, big time. That balance is okay if your second hand is there keeping it steady at all times, but what if the second hand swats at a bee for a second... then you have five pounds balanced on the wrist in a wine glass position, as opposed to the much stronger palm-up position or in a natural hang (unless you don't mind your wrist doing a 180 rotation with a 5 lb load on it).
Adapting a pistol stick to an rb is not clever engineering, sorry. It's a bad idea. Anyway what would I know about torque and moment of inertia; I am just a physicist.
You know what, this really isn't worth discussing. As previously noted, people have been happily using the L grip for ages. Enough said.
