Triple X fin set up

I have a 2009 Triple X Slasher Pro X Surf Style Wakesurfer. Just wondering how easily it would be to switch fins from this board. it came with these little 1.75 "wake" style fins. All I see on wake surfboards lately are larger more surf style fins. (even their new boards come with them) I have read that these can generate more speed and control.

does anyone know if i can change these fins out? i know some boards have "fin boxes" or something, while others use a two screw wakeboard type instalation. any help would be, well, helpful.

thanks
