The new Nike 'covert' collection has the Performance and Tour options. The new technology can allow the player now to adjust the angle of the clubface up to 5 degrees. This new innovation will most definately create more options for the golfer. A great design with a cavity back design. This gives the clubhead much more stability but also enlargens the sweet spot due to the weight being distributed to the heel and toe.
Coming for sale in Feb 2013 :)
