What we did

Seven testers -- handicaps: 2, 3, 5, 8, 9, 10, 11—hit dozens of balls with the four test models. Clubs had 20 to 22 degrees of loft. Hooked up to a launch monitor, the testers hit clubs in varying order. Only well-struck shots were recorded, and we averaged the testers' totals. Here's how the clubs fared.
