TaylorMade Qi4D Review

Qi4D is the first TaylorMade flagship in years whose headline is not a single number. Four movable weights, two at nine grams and two at four, sit in a track that lets a fitter move the head between speed, stability and bias settings without changing heads, and the 60X Carbon Twist face carries a new roll radius that the company claims halves spin variation between high and low strikes. That claim survives a launch monitor.

Thin ones climb instead of knuckling, high strikes stop ballooning, and the carry spread across a bucket of balls tightens against Qi35, which was already the best driver in the line. The aerodynamic work is worth a little over a mile an hour of ball speed, a couple of yards rather than a revolution. It comes in 8, 9, 10.5 and 12 degrees, sounds firm and low rather than tinny, and at $649.99 it is the most expensive driver the company sells. Price is the only grade it does not win outright, and it is still the head everything else gets measured against.
