Qi10 Max Driver - Left Hand/9 degree/Stiff Flex Introducing the Qi10 Max driver, experience TaylorMade speed with the forgiveness of 10K inertia. The Qi10 Max features a shallower head shape that extends from front-to-back and significantly increases inertia by allowing mass to be placed further away from the center of the clubhead. The higher the inertia the more forgiving the driver.
