Quad fin settings

[Cuesta]

Hi there,
I have two quads, the 77 and 87 from 15 months ago. They are the very best boards that I ever had. I am 1,73 tall and 65 kg.
In order to improve my skills, please, I would like to know what is the better settings of the fins, depending or of the wind direction, and of the wave heigh.
Always I use the side shore setting, and from 8 to 14 m/m from the front for the rear fins.
If the wave heigh increase, is better to shorter de distance or opposite increasing that one?
With side shore, on shore, or offshore, what is the best position, more or less distance?
I will appreciate your answer.
Thanks in advance
Cuesta
