Back in January, Team TaylorMade's Rory McIlroy visited The Kingdom in Carlsbad, Calif. to get his new equipment dialed in. Toward the end of the session, he was presented with a brand-new prototype of what would become the all-new P·7MB irons from TaylorMade. This type of player testing is crucial for our R&D teams in discerning what the top players in the world are looking for in terms of feedback and performance from a player's iron. Rory also has a crack at testing the all-new P·7MC irons in the last bit of this video. How pure is that sound?
