I'm fairly reluctant to change my gear but was swept away by the i15 driver it just looks superb, and feels great off the face, its added about 10 yards to my lenghth.. i play off 5 and it's gone straight into my bag, i've held onto my old titleist (d2) driver my pro offered me £100 for it as a trade in so thought better to throw it into my second set.. my local pro was great with the advice and i tried various shaft/head combos on the range with with him and settled on the 700 stiff shaft with 8 degrees loft on the head..
