Many pros prefer the discount Titleist MB 712 Irons
Titleist decided not to release a combo set, blending CB long irons with MB short irons. A player who owns 710 CB or MB irons won't feel much difference if he tries the new Titleist 712 MB Irons or MBs, and that’s by design. The pros who use the clubs—like Rory McIlroy, Geoff Ogilvy and Rickie Fowler—give the company lots of good feedback on them, so Titleist doesn't want to tweak these classic forged blades too much.
The Titleist MB 712 Irons maintains the classic line, profile, solid sound, feel, and shot-shaping precision of classic forgings. However, it also provides modern playability, a benefit resulting from more than thirty years of player research and development, engineering innovation, and advances in manufacturing processes.
