Discraft says this about the Luna: Discraft Stability Rating: 1.0
The Luna is a new putter co-designed from start to finish with Paul McBeth. The Luna features a new and unique plastic blend, combining the fan favorites of Jawbreaker and the durability and extra tackiness of rubber. The melding and firming process of these two materials makes for a great feel in the hand and gives the utmost confidence on the course. The Luna is a great neutral flying putter, making it a staple for heavily wooded and open style courses. This control allows The Luna to take advantage of any angle or putting style and showcase it at it's full potential.
"What I love about this disc is the stability. The Luna is a very neutral flying disc that comes in a lot of different plastics but the 2020 Tour Series is on the overstable side so I can really rip it into the wind if I need or actually get a long flex out of it. If you are a fan of the Big Z, I highly recommend the Tour Z as well." -Paul McBeth
