Callaway Big Bertha Alpha 815 Driver
Price: $449
Callaway’s reborn Big Bertha topped its class in our ClubTest earlier this year. Its replacement, the Big Bertha Alpha 815, takes the signature feature of the equally acclaimed Big Bertha Alpha driver and puts it to work in a model that average Joes can enjoy. The industry-first “gravity core” rod has 10.5 grams of tungsten at one end and 1.5 grams of nylon at the other. You place the rod into the head to move the club’s CG higher or lower to optimize launch, spin and ball speed. The high-CG position (nylon end is closer to the sole) plays like a “mid-spin” driver, while the low-CG position generates 300 rpm less spin. Compared to the current Big Bertha, the Alpha 815 delivers similar mid-spin drives when the rod is in the high-CG position, and 300 rpm less spin in the low-CG position.

The Alpha 815 has the same light, forged composite crown as before, along with a thinner, livelier titanium face that’s made possible by stiffened ribs on the crown and sole, inside the body. Also, removable plugs in the heel and toe (7 gram and 1 gram) can be used to create fade or draw bias. Like its predecessor, the Alpha 815’s adjustable OptiFit hosel provides loft options (from 2° stronger to 1° weaker), as well as neutral or draw settings. Lofts: 9°, 10.5°, 12°.

Its sibling, the Big Bertha Alpha 815 Double Black Diamond ($499), is geared at faster swingers who benefit from less spin. A taller gravity core alters spin by up to 400 rpm. Both models are available Nov. 14.
