Cleveland Launcher DST
Category: Game-Improvement Drivers
We tested: 9°, 10.5°, 12° with Mitsubishi Diamana Red 44 graphite shaft; 9°, 10.5° with Mitsubishi Diamana White 64 graphite shaft

Company line: “Launcher DST is less than 300 grams (25 grams lighter than standard drivers) and has a square face (tending open) with neutral weighting. The longer (45.75″) and lighter (47 grams) shaft creates a 3- to 5-mph increase in swing speed. The club’s ‘variable face thickness’ produces a higher coefficient of restitution (COR) on off-center hits.”
