The TF2 is designed to help the new generation of thruster boards that have wider tails and wider noses, to pivot more on wave conditions allowing for tighter turns.
This fin has a straighter leading edge entry and less tip providing more manoeuvrability and making the board pivot better. The profile maximum thickness has been increased making your board a bit more turny. Leading edge entry is sharper allowing to reach full speed. This fin has been designed to be used with regular MFC Thruster sides fins.
