The Luna is the first putter in the Paul McBeth line for Discraft. It is his primary putter and it more overstable than a lot of other putters. It works great as a low-glide, beadless putter for players who putt with a lot of confidence. 
 
Discraft Putter Line plastic was a hybrid of the original Pro-D base plastic to upgrade it for increased durability and grip. This 2021 update made the putters feel better for use in differing weather conditions and made it more of a mid-grade plastic blend.
