Callaway’s Big Bertha 1.5 Mini Driver was designed for player who prefers the look of a fairway wood at address as opposed to a driver. However the Big Bertha Mini is about 35% larger than a typical fairway so it can yield greater distance off the tee, so it can effectively replace your driver. In addition to a larger head size it also has the higher MOI of a typical driver to produce a high launching consistent ball flight. The Big Bertha Mini has Callaway’s Forged Hyper Speed Face Cup as well as a Forged Composite Crown and a cambered Warbird sole. The Warbird sole makes it easy to hit off of the fairway. The Mini also has the ability to change the loft and lie so you can fine tune your shot shape to the way you like it.
