These bad boys are pretty limited so hopefully this will push Callaway to make some more! If you are interested please touch base so we can put you on the growing list. Thanks!

Phil: “This year I have the best driver I’ve ever hit [Big Bertha Alpha] that lowers my spin rate just like my three-wood. I drive it longer and straighter with my driver than I did with my three-wood,” he added. “It’s a whole different weapon in my arsenal now and if I drive the ball well, like I have been in practice and in the off-season, heading into this 2014 season it could be the best year of my career for that simple reason.”
