Odyssey Ai-ONE Square 2 Square Jailbird Center Shaft putter

Zero torque, 4.0 of 5 for forgiveness

Odyssey's 2025 toe-up Jailbird: a centre-shafted mallet that, in Odyssey's words, is inclined to stay square to your path, in either hand at 33, 34 or 35 inches. Odyssey still sells the Ai-ONE Square 2 Square Jailbird Center Shaft new, and the Ai-DUAL Square 2 Square Jailbird Center Shaft replaced it.

What changed in the Ai-DUAL Square 2 Square Jailbird Center Shaft

Both are Odyssey's Square 2 Square Jailbird: a centre-shafted mallet that rests toe-up, with 2° of forward shaft lean, 3° of loft, a 72° lie and a 360g head, at 33, 34 or 35 inches in either hand. The Ai-DUAL swaps the Ai-ONE insert (an aluminium backer behind a White Hot urethane face) for a two-layer urethane insert with a deeper face groove, which Odyssey says improves forward roll. It also comes with the heavier, stiffer SL 120 shaft in place of the SL 90, and a reverse taper grip shaped to the shaft lean, which is an extra-cost option on the Ai-ONE.

Odyssey still sells the Ai-ONE Jailbird new, so compare the prices in the table: when the Ai-DUAL costs the same or less, it is the better buy. Choose the Ai-ONE used, or when it is cheaper, for the same toe-up head; choose the Ai-DUAL for the two-layer insert and the heavier shaft.

How the 4.0 adds up

The forgiveness score is our reading of what Odyssey publishes about the head, from 1 to 5. It is not a test result. How every score works.

The parts of the forgiveness score
PartPointsWhy
Head type 4 Zero-torque build: the shaft sits at the balance point, so the face turns less during the stroke.

The score rates the head only. Length and hand decide which version you buy, not how forgiving it is.
