Have you tried the Dane Reynolds Fins ???

Powerfully unpredictable. Those two words perfectly describe Dane Reynolds surfing. The new Dane fin is the next level in performance, power and progression. " They are  slightly more upright with larger side fins and a smaller center fin. I find they work  in tight transitions, but have a lot of drive. These fins loosen and liven up my boards.-Dane Reynolds --Made with bits of real panther.  Available in Small, Medium and Large.
