I posted some picture of my fin setups that may be of interest to you, in the Uncle Jaffa's fin Primer.
Unfortunately the fin companies haven't made a generic fin box so some designs are limited to the box or plugs that come with the board.
I am finding the C drives great for pushing the high line in hollower waves to get that extra bit of speed. When I can't use the C drive fins the futures vectors do the same job. By I can't go head to head with them as the fitting systems are entirely different.
