The Progression 13.5 inch tail is a tuned up version of the shiv tail from their combo 3packs. Designed by Clifford Coetzer, the progression tail is supposed to unlock turning, lower stall speed and give extra pump. At the same time, the progression tail is supposed to be faster and more efficient through the water.
