Had a chance to play the MM ball today and have to say, it is a great ball. I played the entire 18 with it to see how durable it is and it passed with flying colors. Had a couple of branch balls along with a bunker shot and it had one small spot on it with keeping it's color.
For me, it was a powerful trajectory off the driver and fairway woods. Super soft (which I prefer) off the irons, wedges and putter. The yardages were consistent with what I'm used to throughout the bag.
I did play the back 9 with the MM and Kirkland to see how they were against each other. Both were close but the Kirkland spins and balloons a tiny bit more with the driver and woods for me, so I'll keep giving the MM a go. You cannot go wrong with either for the performance versus the price.
FWIW, I'm an 8 cap.
