No verdict, on purpose

What the brands claim Manufacturer claim

4 claims

Odyssey Ai-ONE #1 CH

  • Odyssey says the AI-shaped backer behind the insert evens out ball speed on off-centre hits.
  • Steadier speed across the face is claimed to tighten dispersion and distance control.

Odyssey Ai-DUAL #1

  • Odyssey says the two-layer Ai-DUAL face holds ball speed steadier across the hitting area.
  • A soft outer urethane layer over a firmer core is meant to give a soft strike without a dead feel.

Our take Our assessment (based on published specs)

2 min read

Same shape, same brand, two generations apart, and the published numbers move in a direction worth noticing.

The Ai-ONE #1 has 47° of toe hang; the Ai-DUAL #1 has 40°. Both are crank-hosel blades at 3.0° of loft and 70° of lie, in 33", 34" and 35", both hands. Head weight goes from 355 g to 350 g.

The face is the headline: the Ai-ONE's insert is a contoured aluminium backer behind a White Hot urethane face, while the Ai-DUAL uses two layers, a soft urethane outer over a firm inner. Both are Odyssey's own descriptions, and neither is something we've tested.

Price went from $299.99 to $349.99 at launch.

Seven degrees of toe hang is a real difference if your stroke has a pronounced arc — it's also the kind of thing that only means something with a ball, a green and your own hands.
