The biggest difference is control over ball flight. The Qi4D has four movable weights that shift the centre of gravity toward a draw, a fade or a more penetrating flight, and testers found its spin stayed in a well-controlled mid-to-low window. Reviews of the Stealth 2 disagreed on spin, with some finding it too low and others too high, and its shot shape varied from test to test.
Both heads are 460cc at 10.5° with a 45.75-inch length and a carbon face, and both are praised for forgiveness and a crisp sound. The Stealth 2's red-and-black look was widely liked. Some testers found the Qi4D's face glare and visible grooves distracting.
