Quad
Quads are a bit of a different journey for everyone. We have made and had success with these set up as a fish configuration or a twin fin configuration. I feel that because of the amount fin area the fins need to be quite small so that the board is not ruling you, you are ruling the board. However, in saying that I have made them for guys who've had a few Quads and prefer the fins at standard size, ie FCS 5s and 3s.
I feel they are viable in small to medium waves and they are really drivey.
