Choose the size of your fins based on your weight. If you want to increase the maneuverability of your surfboard, choose fins with a straight outline (more pivot, smaller sweep angle) and a normal base (less drive). If you want to boost the speed, hold, and control of your surfboard, choose fins a bit larger than your normal size, with a wide base (more drive), and an outline with more sweep (less pivot).
