Fin Advice for Magic Carpet!!

Recently bought a 6'8 tiki flying carpet, really pleased with it, but its my first board thats shorter than 9 foot and im wondering what the best fin placement is for me.
ive got a nice selection some standard style fins and a True Ames Greenough Stage-6 Fin 8 inch, which is amazing on one of my long boards.
the carpet is setup for thrusters and a longboard fin, but i'm not sure to go for a singlefin setup, maybe with my stage 6 fin, or try thrusters, or just leave whats on it at the moment.
im mainly surfing 2-5ft waves, nothing scary! im 6 foot and weigh about 175 pounds.
any advise would be great! thanks,
