"Speed Bridge" technology that increases head rigidity has been sublimated into a "cap back design" integrated with the badge.The SIM 2 MAX iron has a high trajectory, high muzzle velocity, a toned look, and a pleasant hitting feel similar to that of a forged iron.
Well made and good feel. Not quite as soft a feel on impact as the SIM 2 Max irons though. But I am not sure going for the Sim 2s is worth the extra price. On a personal note, shaft was too stiff for my swing. (Left everything right.) Switching to regular. No reflection on the club and shaft. (Just getting old!)
