For me, the new Nike putter M1, has shown to be a great upgrade in the very little time I've used it.
BUT
That's upgrading from the Max and Rossa putter. Had I kept the L96 Versa, I may have not noticed the added benefits as much. I just got way too lazy with the putting and the Max and Rossa were keeping me lazy. I wasn't spending enough time reading putts and hoping that missing the ding against break would help...... wasn't the best train of thought for wanting to make putts.
Now, with the added benefits of the new L101 Nike, I actually slow down and take the time to study my putts. The added precision and balance can only help show how far off I was on my reads. In time, I can only hope that I learn how to read my putts better based on that.
Putting used to be my favorite part of the game both here and real golf. Maybe this will help restore some enjoyment in the game for me. Heck, it may even help my real life putting since I started getting real lazy on the real putting greens too.
