“Named for its sub-30-percent CG, the Sub 30 uses a dual-material copper-infused aluminum and copolymer face insert for soft roll off high-MOI heads. Face-balanced shapes fit a straight stroke.”

The 2007 Sub 30 was Never Compromise's forgiveness flagship for its price point: a mallet built around a dual-material copper-infused-aluminum-and-polymer face insert, with a taller insert height specifically engineered to reduce distance loss on high off-center strikes. Cleveland Golf marketed it as the softest-feeling putter in the Never Compromise range, wrapped in a matte black finish that multiple reviewers singled out as some of the best-looking work the brand ever produced. It came in a spread of head shapes (Type 20 blade through Type 50 mallet) to cover different stroke styles under one insert technology, which is how a single 'Sub 30' name ended up describing putters with meaningfully different geometries.

Unusually broad, consistently positive independent coverage for a mid-tier putter line: GolfWRX, PutterZone, Golfmagic (twice), Today's Golfer and InTheHoleGolf all reviewed different Sub 30 variants, and one model hit a rare 5/5 on golfreview.com (albeit on a small 6-review sample). It is largely forgotten today outside secondhand listings, but the review spread suggests it earned genuine word-of-mouth in its moment rather than just running on ad copy.

Golfers who mis-hit putts vertically on the face as often as side to side, and who want a soft-but-defined feel rather than a firm milled click. A strong choice for a mid-to-high handicapper wanting distance control without paying big-brand mallet prices; a low-handicap blade purist would find the insert feel less precise than a milled face.

• Face insert is described as dual-material: copper-infused aluminum plus polymer, aimed at both feel and distance control.
• Insert height is taller than typical, specifically to reduce distance loss on high (off-center-vertically) strikes.
• Sold across multiple head shapes under one name — Type 20 (blade) through Type 50 (mallet) — so 'Sub 30' covers a family, not one geometry.
• One Sub 30 S2 variant earned a 5/5 rating on golfreview.com from users.
• Marketed by Cleveland Golf as the softest-feeling putter in the Never Compromise range at the time.

Launched in 2007 in the same Never Compromise catalog year as the Milled Series blade, giving the brand a genuine good/better spread — insert mallet for forgiveness, milled blade for tradition. It arrived as insert-face mallets (Odyssey White Hot, TaylorMade Rossa) were the dominant game-improvement putter technology of the mid-2000s, with Sub 30 as Never Compromise's answer to that trend rather than a category leader.

Cheap for the review attention it got: private-party prices for a clean Sub 30 typically run $35-$80 depending on head type and shaft length, per eBay and 2nd Swing listings — there is no reconditioned-retail inflation to flag here since it is not heavily stocked by graded-used chains. It is a genuine bargain for the amount of forgiveness engineering built into the insert.
