Callaway Odyssey Square 2 Square Ai-Dual Seven Putter

Odyssey runs the Seven mallet in two of its lines at once and this is the Square 2 Square version, which changes the hosel and leaves the head alone. The neck holds the face square rather than letting it rotate, so the mallet doesn't need a stroke that squares it. Ai-Dual insert, 120 gram shaft, reverse taper grip. Three lengths, black or red.

Same shape, different philosophy, is a fair summary of what separates this from the Ai-Dual Seven DB. That model uses a double bend hosel and Odyssey's lighter 90 gram shaft with a conventional pistol grip, where everything about the Square 2 Square build is aimed at taking rotation out of the equation. Right hand only here. If you've hit a Seven before and liked the head but fought the face, this is the version that addresses it.
