During my coaching with Robert-Jan Derksen, he would always refer this as the ‘Middle of the Middle’, his increased awareness of the exact location of the sweet spot was vital feedback for his practice! Simply peel off the adhesive backing off the ‘Putting Clip’, then line it up so the face matches the sweet spot of your putter.
In the three examples below, the first highlights a centre strike, with minimal club face twist 0.07 degrees. The second example shows the ball being struck out of the heel (resulting in the club face closing -1.23º) with the third example being struck towards the toe and as a result opening 0.63º and imparting unwanted side spin (hook) as a result, otherwise referred to as ‘the gear effect’. Making contact with the ‘Middle of the Middle’ and the putter doesn’t twist, ensuring consistent pace and clubface alignment at impact. Miss the spot and there is no sound, the ball jumps sideways… ensure solid contact, how many can you hit in the sweet spot in a row?
Practicing with the ‘Putting Clips’ will help you to learn whether you’re hitting the toe, heel. top or bottom on your putter. Most players have a consistent pattern of how they miss putts. By using the ‘Putting Clips’ it will help you identify your miss and provide you with valuable feedback during each putt. Your ultimate aim to forget you even have the ‘Putting Clips on your putter during practice! Good Luck, it worked for me
