A picture's worth a thousand words - if you go to my user profile by clicking on ChrisNZ to your left, and going to my user profile, then I've posted a profile picture of Sergio with some lines drawn on it to demonstrate, how, with the aid of a mirror, Sergio could see the clubshaft plane at address looking 'up the plane' so it appears as a line. (No way of uploading pictures for me, so this'll have to do as a work around!)

The black lines represent the line of sight. The short red line by the ball represents the mirror, and the long red line shows the angle of the mirror (halfway between the two black lines).

Does this help?

With you Chris ! To complete the package all you need is to place the mirror below the gound -on plane -i.e.just move it back down the long red line so you can make sure you are on your true plane and not hovering the club so you don't break the mirror!.Good stuff
