For heavy hitters, Graphite Design will soon release the new Tour AD Throttle line of shafts, made specifically for high swing speed players.

All four models are 47 inches long with a stiff tip, a high bend point and low torque. That combination, according to Graphite Design, should produce a lower ball flight and reduce driver spin. Each shaft has a suggested retail price of $175.

The names of the different versions of the Throttle shafts are designed to also get your juices flowing on the tee.

Turbo Charged = regular
Super Charged = stiff
Nitrous Charged = extra stiff
Methane Charged = double extra still
