What the fitting tests show
Cool Clubs tested all three heads on a robot and added them to its fitting matrix. At a 95 mph clubhead speed, its center-strike results put the LS at 1,813 rpm of spin, the standard RKT at 2,171 rpm and the MAX at 2,530 rpm. Carry distances in that test were much closer: 226.1, 229.4 and 230.1 yards, respectively.
That spread gives a home-simulator golfer something useful to compare during a fitting. The lowest-spin head did not produce the longest carry in this particular test. Launch angle and the rest of the ball flight still mattered: the MAX launched at 12.2 degrees, compared with 10.4 for the LS and 10.6 for the standard model.
Cool Clubs also published a hitting-bay video with the three drivers. It is a September introduction to the same family, included here as background to the U.S. retail launch.
