Hi. I've owned a quatro quad ls 75 2012, a quatro quad 80 2015 and a quatro cube 81 2018. The only one which surfs well in my opinion is the quad 80 in spite of having the widest tail of the three. I prefer the goyas, both tris and quad surf looser.
Has someone changed the fins of the cube 81 to turn looser and got it? How? K4 fins? Which model and size?
Thanks
