Discraft Luna Review: Paul McBeth’s Signature Overstable Putter
The Discraft Luna is Paul McBeth's signature putter and one of the most talked-about putters in modern disc golf. Its 3/3/0/3 flight numbers describe an overstable putter that resists turning and finishes with a strong left fade - completely different from the neutral flight of the Dynamic Discs Judge or Innova Aviar. McBeth chooses it for its reliability in wind and its firm, comfortable feel. For players who want a putter that won't deviate from its line, the Luna delivers.

Who Should Throw the Discraft Luna?
The Luna is a specific-purpose putter. It is not a "neutral" putter like the Judge or Aviar that beginners can use for everything - its overstability makes it better suited for players who know when to reach for an overstable putter vs a neutral one.
- Beginners: The Luna's Fade 3 will push putts left predictably - not ideal for learning basic putting. Start with a neutral putter like the Judge. Add the Luna once you understand disc stability and have specific situations where overstability is needed.
- Intermediate players: Useful as a windy-day putter and approach disc. When headwinds would push a neutral putter offline, the Luna holds its line. Also excellent for approach shots that need a hard left finish.
- Advanced players: The Luna earns a permanent bag spot. McBeth uses it for putting because its overstability provides consistent lines that don't require adjusting for slight release variations - the disc corrects and fades to the basket regardless.
How the Discraft Luna Flies
The Luna's 0 Turn means it won't deviate right regardless of throwing speed. The Fade 3 gives it a reliable left finish every time. For putting: aimed at the basket's right side, it fades to the left chain as it approaches. In headwinds, where a neutral putter might flip off-line, the Luna maintains its overstable character and completes the fade reliably.
The Glide 3 (low) means the Luna drops faster than high-glide neutral putters. This is intentional for McBeth's style - a lower glide means the disc gets to the basket more directly rather than floating past. Some players love this; others prefer the floating quality of higher-glide putters.
As an approach disc: the Luna covers 50-150 feet reliably, always finishing left. On hyzer: it holds the angle and sets down flat. For forehand approach throws: the overstability prevents flip. It is a more specific use-case approach disc than the neutral-flying Judge.
Luna vs Zone vs Judge: Choosing Your Putter/Approach Disc
- Luna (3/3/0/3): Overstable putter, slower speed, used for putting in wind and approach shots. Similar overstability to Zone but with putter rim.
- Zone (4/3/0/3): Overstable approach disc, slightly faster, purpose-built for skip shots and longer approach shots. Not a putting disc.
- Judge (2/4/0/1): Neutral putter for all skill levels. Goes straight, gentle fade. The "everything putter."
Discraft Luna Plastics Compared
- Z Line: Standard, firm, slick. Most overstable Luna. Good for headwind putting.
- ESP: Grippy, durable, slightly more understable than Z. Most popular choice. Around $18-20.
- Big Z: Flexible, grippy, most understable Luna. Good for cold weather and players who want the Luna to turn just slightly less aggressively.
- Z FLX: Flexible Z plastic. Better cold-weather grip, similar flight to standard Z.
Pros

- Paul McBeth's signature disc - world-champion proven
- Reliable approach disc for hard left-finishing shots
- Comfortable, firm feel popular with experienced players
Cons
- Not beginner-friendly - the Fade 3 will push putts left unexpectedly

- A specialty disc, not an all-purpose putter
Frequently Asked Questions
Why does Paul McBeth use an overstable putter?
McBeth prefers the Luna because its overstability gives him consistent lines that don't require fine-tuning for wind or release variations. When you generate enough arm speed to reach the Luna's flight window, the disc corrects and fades reliably. At professional arm speeds, overstable putters provide more predictable results than neutral ones in varied conditions.
Is the Luna good for circle-2 putting (10-20 meters)?
Yes, with practice. On longer putts where you need to throw harder, the Luna's overstability becomes an advantage - it holds its line through the wind and finishes reliably at the chains. Aim at the right side of the basket and let the fade bring it in. This is a different putting style than most beginners learn, but it is highly effective once dialed in.
What is the difference between the Luna and Zone as approach discs?
Both are overstable and finish left reliably. The Zone (Speed 4) covers more ground and is better for 100-200 foot approaches. The Luna (Speed 3) is slower and better for shorter approaches where you need precision over distance. The Zone also has a wider rim, which some players prefer for skip shots. Use the Zone for longer approaches, the Luna for shorter precision work.
