Callaway Odyssey Square 2 Square Tri-Hot Black Rossie Putter

Rossie is the odd one out in Odyssey's Square 2 Square line, the only appearance of that mallet outline among heads otherwise split between Jailbirds and Sevens. Black is the only finish. A Square 2 Square hosel holds the face square through the stroke, so nothing rotates, and the Ai-Dual White Hot insert sits behind it.

Head shape is the entire decision at this point in the range. Every Tri-Hot model shares the same insert, the same hosel, the same Pistol Plus grip and the same 120 gram black steel shaft, which leaves outline, finish and build length as the only things that move. Three lengths, right hand only. Set the Rossie next to a Jailbird and pick the one you can look at, because the specification won't separate them and there's nothing else left.
