It isn't completely heel shafted like the Odyssey, there was a little wiggle room there in terms of bending to give it a more SBST workability.
IMO outside of a similar head shape they are totally different putters. Toe hang makes a huge difference in the feel as does the weight and the QB is not truly heel shafted like the #9s are.
Exactly. It's like a cross between heel shafted and a flow neck. Not a plumbers neck by any means but a nice hybrid neck style that could be bent to suit a variety of strokes.
