Chosing components - plane and plane shifts

[armourall]

Bulldog,

I'm not sure if there is one "correct" posture, and that may be a variable in setting up on different planes, but I'd like to tag my own question on to yours:

Assuming a level left wrist at address, what adjustments would you need to make at address to use an Elbow Plane rather than a Turned Shoulder Plane? (Would the left hand grip--and Accumulator #3 angle-- need to change?, etc.) Please be as specific as possible.
