Collin Morikawa is one of the best iron players in the game of golf. So we had him hit and compare the new P·790 and P·7CB irons to have him, in his own words, explain the differences between the two.
Collin hits both, talking spin and launch angles and what he looks for at the top of his bag. Collin goes back and forth between a P·7CB 4- and a P·770 4-iron, and explains how it is course dependent.
