Deadkooks ImpulseDesigned as a suitable template for a wide range of surfers of varying sizes across boards from 9'0 upwards. This fin has ample base to give a reliable feeling when nose riding, while maintaining area towards the tip to keep things tight and increase drive through turns. We wanted to keep flex to a minimum on this, as too much flex in a fin this size can lead to the washing off of speed through turns. Also available: DeadKooks Utopia
