I know you can MAY not touch the line of your putt. I also know you probably SHOULD not touch anything close to the line of the putt. but...Is is mentioned anywhere in the rules or decisions about the how stringent this is to be interpreted. To illustrate (using a diagram I stole from something demonstrating an Aimpoint point... If I or my caddy were to touch the line going off to the right once it passed the line of the putt, would that be permissable. Could my caddy touch the green at the spot where the words aimpoint appear? My interpretration of the rule is that we could. Of course we would have to deal with the resultant kerfufle and the subsequent discussion of what really is the line of the putt..
Anyone have any intelligence on this?
