Cobra Darkspeed 

Cobra used AI software to design the Darkspeed’s thinner and larger L-shaped cup face resulting in improved ball speed from the variable thickness configuration. Cobra says up to 25% more face flection at impact means substantially better ball speeds and more distance. The hollow cavity back head is filled with foam microspheres and uses an internal PWR-BRIDGE weight. The ONE Length option is also available. 7-club set steel shafts $999, graphite shafts $1,099
