The System Q Fairways are the perfect match to the Power Play System Q driver series. The unique sole design and positioning of the rear weights ensures a higher launch angle and added forgiveness, even for those difficult trouble shots. The head comes preset with two 6 gram tungsten screws, but the weights are removable. Additional weight screws (2g, 4g, 8g and 10g) may be purchased separately. Adjustable rear weight ports allow you to configure the clubhead to either heavier of lighter swingweights or to accommodate for different length options. The weights can also be unbalanced to possibly correct for a push or pulled tendency. Conforms with USGA Rules.
