The big difference for me was a better putter BUT also the balls.
Why the balls? Because dinging the meter was my biggest challenge, when I do I sink say 75% of the putts, when I miss the ding maybe 15% of putts.
What is helping me in a big way is a ball that slows down the meter and also using a longer putter on some putts (like 60 foot putter for a 12 foot putt) which means the meter has less travel distance and a little easier to ding the meter.
GL and keep practicing!
