Callaway Big Bertha OS irons Look Feel ClubTest 2017

A standout-design suggests high MOI and gives testers confidence that they'll hit straight, soaring shots; most guys go for the gunmetal finish and technology neatly sealed away in the cavity.

Weighting makes you aware of the head during the swing, improving timing and clubface control; feels powerful at impact; balls seem to compress and jump off the face quickly and crisply; strong as oak on all but the worst misses.

Might be its best feature; makes you look like half your handicap, with an oversize sweet spot to keep misses online; surprising accuracy is great for playing target golf.
