Hi everyone

I have a small sup 7'2x25 73L that I use as a regular surfboard in very weak waves.
I have trouble getting past "dead" sections, and was wondering as to what would be the best way of setting up the fins. It has 4 future boxes and on us-box, so pretty much all options are available. How would you set it up to optimize it for weak waves?
