Optimal Single Fin

I am about to make a glass on single fin for my board in the works which is 7’6" x 12" x 23" x 17" x 3" and is a round/roundpin tail. I have no clue as to what fin to make though, as this is my first time dealing with single fins. What fin would you recommend for this board and for waves between 2’-6’. Pictures of recommended fins that could be used as templates would be appreciated. Oh, and after reading the archives I think the spitfire fin sounds like it fits these parameters fairly well, do you agree? Also what is the foil like on a spitfire? Thanks for the input.
