What JerseyThursday proposed is that you may carry Medicus on the course and use it for training as long as you do not make a stroke at a/the ball. IMO that is correct as it is a club and not a (mere) training aid. However, one would take penalties for carrying a non-conforming club and not using it. So in the end, the player would get 4 PS but would not be DQ'd. Are we now in agreement?
