I have been working with David MacKenzie for several years and have really learned and benefitted from his wealth of information. How to utilize my time to practice and prepare for tournaments has been extremely helpful as well. With 11 grandchildren I spend much less time practicing these days! Also using the mental score card in competition has definitely helped me solidify my pre and post shot routine in competition. My scores are considerably better in tournament play vs casual play. Thanks David!
