Which surfboard fin to chose??

Hello
My name is Filipe and i'm from Portugal. I live near Peniche and so, i started surfing as a sport/hobby.
I had lessons and after that a bought my first board. A Southpoint 7.6
ou can see it here. http://www.pi-watersports.com/html/body_southpoint.html
My doubt now is about the fins. I want to change the fins, but i don't know wich one to chosse.
The fins are:

This is maybe my favourite, because i'm still starting and my board besides the size it's a very "lively" board and i'm trying to find more speed and stability.

A smaller size but i believe it would be enough maybe.

A balanced fin. A mid-term i believe.
