Cobra King F9 Speedback 4-iron

“Fowler also carries two 4-irons, including a Cobra F9 Speedback 4-iron built at 3-iron length with a Graphite Design graphite shaft that he used frequently to tee off with.”

“In a recent post-round interview, Fowler called Cobra's F9 Speedback 4-iron—which he adopted almost immediately upon its debut—a "sneaky weapon."”

“On Tuesday, Fowler had two different Cobra King F9 Speedback long irons in his bag.”
