The Wilson Staff Shockwave driver is 10% lighter than standard drivers, with a 5g tungsten weight set deep into the head giving a high ball flight. Variable face thickness gives a sweet spot that is twice as wide as a constant thickness driver.
A great-looking club with a large sweet spot. The alignment aid is fussy but this is the only real criticism for a decent driver at a reasonable price. It produces a solid, if unspectacular, impact noise.
