Titleist 620 MB Irons

Muscle backs get simpler every year and the 620 MB is close to the end point. Forged carbon steel, 35 degree 7-iron, 3-PW, and True Temper Dynamic Gold Tour Issue as the only stock shaft in regular, stiff or X-stiff. Left-handed sets are made, an option this corner of the market usually skips. The Titleist Universal 360 grip completes it.

Six years in the range without replacement is unusual, and it reflects the simple fact that a blade design has nowhere left to go once the shape is right. The 620 CB matches the loft with a cavity behind the ball, and plenty of MB buyers take a few CB long irons alongside it. Titleist's T100 is the modern alternative at 33 degrees. Anyone still playing full muscle backs already knows which they want.
