With a Forged Hyper Speed Face Cup for ball speed and a Modern Warbird Sole that makes it easy to hit….the Great Big Bertha is back and should be in your bag! High Ball Speeds From Cup Face Technology:Callaway are serious about giving you the most distance in a fairway wood, and They put their Forged Hyper Speed Face Cup to show that we mean business. It’s designed for high speeds that make the ball go a long way on center hits and off-center hits. Ultimate Playability and Control:The head is larger than Callaway's typical fairway wood, and that extra surface area leads to a higher MOI for more forgiveness. Callaway also added their legendary Warbird Soleplate which makes the club easy to hit from a variety of lies with a mid-launching trajectory. Special Heavenwood and Divine Nine Options:These two clubs have a unique combination and tighter dispersion than you might get from your regular club configuration. The Heavenwood (20.5* loft, 43” shaft) and Divine Nine (24*, 42” shaft) could give you the perfect gapping for your bag. OptiFit Adjustability:Tune the fairway wood to the settings you want to play with our 8-way adjustability. You can add loft, take loft off or adjust the lie angle to fit your swingStandard Shafts: Mitsubishi Bassara E 42 Mid-high torque ideal for Women.
