If you are a real aggressive rider I would be concerned out weighing a soft board with the flex of a 3 by 20 lbs. Although reverse camber allows us to ride shorter boards, out weighting them will decrease its float on a deep day.
Check out the Prophecy. Comes in Re:flex with a response of a 6 and has a dual component base plate for more board feel underfoot. Add a react strap and a lightweight mesh high-back that conforms to your boot.
