Chris you had me very excited there ...but ..how do you see the straight plane line trace unless you are on the "eye" plane.From what I understand from your description ,you will be looking between....lets say the turned shoulder plane and the "eye "plane.From address there is no way you could look along the plane line unless you could get your right forearm along the line of your eyes -and if you did your wrists would be uncocked and.....that is not a procedure .I really wanted that to work ! It would have made all our lives a lot easier

Don't try to swing on the eye plane - and definitely don't try to get your right forearm on the eyeline!!!!

What the mirror is doing is reflecting (or is it refracting - I don't know!) your eye plane onto a different plane. Imagine standing looking straight down onto a mirror (looking in a vertical plane) which is angled at 45 degrees to the ground. what you'll see in the mirror will be in a horizontal plane - kind of like the principal behind a periscope. The idea for this aid is the same, but your changing your "eye plane" to a turned shoulder plane, or elbow plane, or whatever.

To get the idea get a mirror and put it on your target line lying flat on the ground. Now lift up the edge which is furthest from you at address (the one parallel to your target line). Lift it up so the angle it forms with the ground is about 20 degrees or so. Put something under it so it stays there. Now take your address position so you can see your torso and hands in the mirror. now simulate a basic motion through the hitting area. See how your hands trace a pretty straight line (that is their reflection in the mirror)? The mirror may need to be adjusted slightly in terms of angle to get it dead straight depending on your height and plane angle used.

If you can do this, I think you'll get the idea.
