Callaway Odyssey Ai-Dual Double Wide Putter

Double Wide describes the head and Ai-Dual describes the face. The insert is built in two layers, a softer outer skin over a firmer core, which is Odyssey trying to give a putter both a quiet strike and enough energy to hold pace on long putts. A double bend shaft leaves the mid-mallet balancing face up. Three lengths, black, both hands.

Odyssey numbers its putter shafts by weight and this one gets the lightest at 90 grams, which is the standard fitting across the Ai-Dual range. Heavier shafts turn up on the counterbalanced and broomstick builds further up the line. Wide mid-mallets are easy to aim, and that's most of the appeal here. If your stroke doesn't rotate, the geometry asks nothing awkward of it.
