Determine the primary surf you ride, and characteristics you want.
Mushy surf requires a fin that creates incredible amounts of drive and speed right from takeoff. Hollow surf takes a fin that controls the inherent speed of the wave. Midrange rippable surf can take a blend of both. Choose the fins in your riding style category or move one category left for a looser fin and one category to the right for a stiffer fin.
