HP longboard single fin size?

Hey Hey! i have a 9'6" walden magic model (my only high performance longboard) and ive recently taken the sidebites out and put in a 9" fluid foil fin (http://www.ronjonsurfshop.com/store/item.aspx?ItemId=151869)<--- link to fin
ive never personally ridden a "HP" longboard with a single fin setup, and wanted to know what the experts (you guys) think, if it should be longer/wider/fatter , i know the general rule is 1" of fin for every 1' of board but the only fin that i have bigger than my fcs fluid foil 9" is a Ez-Kine hook 9" thats black composite. ( its the same length just a little beefier throughout )
ez-kine hook 9" (http://www.islandwatersports.com/shop/shop/details/569/97/surf/fins/longboard-fins/9in-hook-ez-kine-fin)
reason for going from 2+1 to single fin: im not into "pr0gressive" rip tear and shred longboarding (although i love how precise the magic model is carving or on the nose) and i want to work on trimming/noseriding so single fin was a no brain-er. I don't want to have to pump and carve little "S" turns all the time just to make the wave or do a maneuver, so im thinking i may just use the biggest fin i have (the ezkine) and go from there. really want to get the most drive/trimm speed out of the wave! because with the what, 5-6" box fin and side bites you have to surf the magic model like a shortboard or you wont make the wave.
all your info's will be greatly appreciated, iam going to take the board and bolth the fins out for an afternoon session today at Terra Mar in Carlsbad Ca. (should get bigger later when the tides down here in socal 2-3 occ 4, perfect kooky waves for a kook!)
thanks for your time!
