Rhythm (Neutron) weight:173g Streamline Discs says this aboutThe Rhythm is an awesome understable driver by Axiom. It's designed to be either a great first driver or a line shaping fairway driver for more powerful arms. Lower power players will find the Rhythm to be laser straight with a slight fade at the end. High power players will love the Rhythm for carving up the woods with hyzer flips or natural turnover shots. Find your beat on the course with the Rhythm. Flight Guide Speed 7 Glide 5 High Speed
