Titleist 620 MB
Our take: Muscle-back irons are still popular among better players who want the utmost in workability, feel and distance control. Make no bones about it — they aren’t going to be as forgiving on off-center hits as a cavity-back, but if you’re the kind of player who hits the sweet spot more often than not, a muscle-back design like the 620 MB may be just what you need to take your scoring from the fairway to the next level. “I never have to wonder about Titleist’s blades,” said a tester. “They’re always consistent, regardless of the iron I pick up. I don’t ever want to guess if I’m going to hit my number. These are perfect.”

The details: Featuring a pure muscle design, the 620 MB irons are forged from a single piece of 1025 carbon steel and have reduced offset, a progressive heel-toe length depending on loft, a retooled sole for improved turf interaction and a Project X steel shaft. It’s a set that’s exquisitely crafted for maximum shotmaking playability and comes with a feel you can only get from a forged muscle-back design.
