Playability

Flies higher than others, which makes the long irons easier to handle; brawny head rips through the rough with ease, and is adept at picking balls out of fairway bunkers.

“Tremendously forgiving–and no slouch when it comes to distance.”

Distance Control

This one packs a punch; a few testers hit it up to a full club longer than their own sticks; several other guys notice significant gains on mis-hits.

Cons

Several guys struggle with finesse shots, and would swap out the wedge; some wish for more feedback, while others like a softer feel; can look a little clunky and too much like a hybrid.

Bottom Line

The Big Bertha OS is one of the better irons tested. This mean-looking stick serves up a big dose of forgiveness and length.
