Single fin for a 9'8 FireWire The Gem?

[LISurf]

I'm 5'10, 200 lbs. Located on Long Island. I placed an order for this Longboard. My first real longboard aside from the Wavestorm. Looking for a good single fin for this board. Anyone have any suggestions? I'm partial to Futures but I believe single fin boxes are universal and any fin should fit?

I originally wanted 2+1 fin setup so I could play around with options but I was told the 9'8 only comes in single fin configurations.
