I tried the stack and tilt on the course for the first time after one driving range session and broke 70 for the first time in my life. Talk about results. I was stiffing my short irons and hitting my woods (usually my achilles heel) long and straight. I was also hitting almost a club less than my usual distances.
Can't tell you what a turn around this was. Of late I have been struggling to break 80, in fact I have shot some dismal rounds in the high 80s. My confidence and swing was shot. But then I saw the stack and tilt on this site and checked it out. After one session I birdied the last two holes for a 69. Didn't hurt that I had 27 putts, but I hit 13 of 14 fairways and 12 of 18 greens. And my misses were mostly just a yard or two off.
