Discraft Luna Review: Paul McBeth's Putter, and Whether It Should Be Yours

When the best player in the world co-designs a putter and then actually putts with it for years, people buy it. The Luna has been Paul McBeth’s putter since he joined Discraft, and it’s become the brand’s default putter recommendation. That’s a strong reason to consider it and a weak reason to buy it: what works for a 1050-rated putting stroke doesn’t automatically suit a 900-rated one. This review covers how the Luna actually flies — including why its flight numbers keep changing — what the Rubber Blend feel is, and which players it suits better than an Aviar or a Judge.

Pros

• Slightly overstable for a putter — holds a line in wind that pushes an Aviar around
• Flat top and beadless 1.1 cm rim; excellent for throwing putters off the tee
• Rubber Blend (Jawbreaker + rubber) is one of the grippiest putter plastics made — 'a new and unique plastic blend,' per Discraft
• Rated 4.45/5 across 139 Infinite Discs reviews; McBeth's actual putter
• Sold in more than 40 plastic variants, so there's a feel for every hand

Cons

• Less glide than a Judge and a firmer fade than an Aviar — soft putts drop early
• Discraft's flight numbers were revised (to 3/4/0/2) after release, so listings disagree
• Premium and Tour Series runs are pricey for a putter
• Flat, beadless rim isn't for players who like a deep, beaded grip

About those flight numbers

The Luna is the rare disc whose flight numbers are a story. It launched as a “neutral” putter; Discraft later revised the numbers to 3/4/0/2 and says on the product page that the change was to better reflect how the disc actually flies — the mold never changed. Older retailer listings and Discraft’s own team site still carry earlier figures, so you’ll find 3/3/0/1, 3/3/0/2 and 3/4/0/2 for the same disc. Infinite Discs’ reviewer average — 3 / 3.2 / −0.2 / 2, from 139 owners — is the most useful number: a putter with a touch more speed and finish than an Aviar, and less glide than a Judge.

How the Luna flies

Discraft calls it “a great neutral flying putter” for “heavily wooded and open style courses,” and owners refine that: neutral on a firm throw, slightly overstable on a soft one. Thrown flat with pace it goes straight and finishes with a small, reliable fade; that’s what makes it a good driving putter and a dependable disc in wind, where an Aviar starts to drift. Owners repeatedly describe it as having “more overstability than most putters” and as “a low-glide, beadless putter for players who putt with confidence.”

That last phrase is the honest summary of its putting behaviour. Because the glide is modest and the fade is real, the Luna rewards a firm, flat stroke: put it on line with pace and it hits the chains. Lob it softly or release it with wobble and it drops sooner and drifts left more than an Aviar or Judge would. Confident putters read that as consistency; developing putters read it as unforgiving. Both are right.

What owners actually say

Across 139 Infinite Discs reviews the split is clear and it maps onto skill, not taste. Five-star reviews (two-thirds of the total) come from players who describe themselves as confident or firm putters: they praise the wind resistance, the “locked-in” feel of the flat rim in Rubber Blend, and the fact that one disc handles putts, upshots and the occasional drive. Three-star reviews — about 8% — almost all say some version of “great feel, but I lost strokes to it”: short putts dropping, a left finish on lag putts, a disc that punished a soft release. A small number of owners note that the Rubber Blend softens in summer heat and firms up in winter, which changes the release slightly between seasons; the Big Z and ESP versions don’t.

The recurring purchase pattern is instructive: players who come to the Luna from an Aviar or Judge because of wind tend to stay; players who start on a Luna as their first putter more often move to something with more glide and come back later. That’s the review of a putter with a personality, not a flaw.

Feel: the Rubber Blend

The Luna launched in a plastic Discraft made for it — “a new and unique plastic blend, combining the fan favorites of Jawbreaker and the durability and extra tackiness of rubber” — and Rubber Blend is still the version most owners are describing when they praise the feel. It’s tacky, slightly soft, and grips in cold and wet weather. Combined with the flat top and the beadless 1.1 cm rim, it’s a putter that sits low in the hand and releases cleanly for players who like a flat rim; players who want a deep, beaded grip (Judge, Wizard) will find it thin.

Which plastic?

• Rubber Blend ($17–$19): the original and the default. Tacky, slightly soft, grips in the wet. Buy this first.
• Putter Line ($13): firmer base plastic, cheapest. Good if you like a stiffer putter; beats in faster.
• Jawbreaker ($15–$17): soft and grippy, wears faster than Rubber Blend.
• Big Z / ESP / CryZtal ($17–$22): durable, a touch more stable — the plastics for a throwing Luna.
• Tour Series ($25–$28): premium ESP with McBeth stamps. Same disc, collector price.

Luna vs the putters people cross-shop

More forgiving, cheaper

Innova Aviar Putt & Approach

5.0/5

$9 (DX) – $17 (Star/Champion) approx. street price

Check Price at Infinite Discs

Pros

• Neutral 2/3/0/1 flight; the reference putter and the cheapest way to learn

Cons

• Pushed around more in wind than the Luna

Innova Aviar (2/3/0/1) — the neutral reference, cheaper, and more forgiving of a soft putt. It gets pushed around more in wind, which is the single most common reason owners switch to a Luna. Beadless like the Luna, but with a rounder top. See our Aviar review.

More glide, beaded

Dynamic Discs Judge

4.5/5

$10 (Classic) – $18 (Lucid) approx. street price

Check Price at Infinite Discs

Pros

• 2/4/0/1 with a big bead — floats to the basket on soft putts

Cons

• The bead is love-it-or-hate-it; less stable in wind than the Luna

Dynamic Discs Judge (2/4/0/1) — more glide and a big bead. The Judge floats to the basket on soft putts where the Luna drops; the Luna holds wind where the Judge drifts. The bead decides it for most hands. See our Judge review and Aviar vs Judge.

If you want more overstable

Discraft Zone

5.0/5

$11 (Pro-D/Putter Line) – $25 (ESP/CryZtal/Titanium) approx. street price

Check Price at Infinite Discs

Pros

• 4/3/0/3 — the overstable approach disc; the Luna's stablemate in most Discraft bags

Cons

• Too overstable to putt with for most players

Discraft Zone (4/3/0/3) — not a rival but a partner. The Zone is the overstable approach disc; the Luna is the putter. Most Discraft bags carry both. Our Zone review covers it.

Who should buy the Luna

Buy it if:

• You putt firmly and flat and want a putter that rewards that.
• You play windy courses and your current putter drifts.
• You want one putter for both putting and driving off the tee.
• You like a flat, beadless rim and a tacky plastic.

Look elsewhere if:

• You’re still learning to putt and want maximum forgiveness (→ Aviar, Judge).
• You lob your putts and rely on glide (→ Judge).
• You want a deep, beaded grip (→ Judge, Wizard).
• You need an overstable approach disc, not a putter (→ Zone).

Verdict

The Luna is an excellent putter with a specific personality: slightly overstable, low-glide, flat and tacky, built for a confident stroke and a windy day. That personality is why the best putter in the world uses it and why a beginner might score better with something more neutral. If you already putt well and want a disc that won’t drift, it deserves the hype. If you’re still building a stroke, buy an Aviar or a Judge, learn, and come back — the Luna will still be here, in forty plastics.
