Golf Shop: AEROTECH PowerCoil 65 Wood Shaft

"The Powercoil has been improved for 2004 by optimizing the torsional profile (the amount the shaft twists at different locations along its length) in each flex so these is a Powercoil shaft for every golfer. Like its predecessor, the new Powercoil is designed with a high modulus carbon fiber surface layer oriented in a spiral direction down the shaft for more uniform bending properties during the swing. This Hoop Wind virtually eliminates the oscillation of the head resulting in more consistent contact and reduced shot dispersion. The Powercoil surface layer is oriented in a direction that allows it to load in tension while the club is being twisted during the swing. This imparts a tightening of the outer fibers for a more efficient energy transfer to the ball and greater distance. And since left-handed golfers twist the shaft in the opposite direction, the surface is spiraled in the opposite direction on the left-handed shafts."
