King Cobra Speed Pro S Driver. New for 2007. The King Cobra Speed Pro drivers are the first drivers designed and developed with feedback from the Cobra PGA Tour Staff and are tuned for extreme ball speed players. Featuring a traditional pear-shaped driver head, the Cobra Speed Pro Drivers are designed to create high launch, pro spin conditions and optimal distance. Traditional top-down profile with square to open alignment at address. The Milled Dual-Rhombus Face Insert creates a more efficient face design to further optimise ball speed via maximum Coefficient of Restitution (COR) across the face. Cobra Speed Pro drivers are available in two models - this, the Speed Pro S, features a shallow face and higher MOI of 4,900 for high launch and low-mid spin. The Speed Pro D features a deep face and enhanced MOI of 4,500 for high launch and low spin.
