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

What's wrong with MFC fins? If the stock fins that come with the board are too big for your liking, just try a size smaller.

I think even the older quatro quads are pretty amazing, haven't found anything to complain about.

I rate them amongst the best wave boards ever. I note your idea of looser boards are ones that are not typically known for being really loose - they’d be akin to the Quatro for most folks I think. Its not like you said Pyramid which would of course be.
Thus, have you measured all your setup on the ones u like vs the Quatro? Stance vs fin positions
I find they’re better with the mast base a bit behind centre unless you really need to engage more rail in the bottom turn as they are of course not a full DTL only board. Base to rear a bit improves planing threshold and definitely looseness for me - but as I said I never thought the latter was lacking

Just contact k4 uk direct.An incinerator set will loosen board considerably as they are low area for size.

Qube will most likely work well as a twin also.

Apart from other good opinions, I've found this review. I completey agree. See "It inittially..." Maybe this is more related to light riders.

That implies push it harder in bottom turn but you’re saying it’s not loose enough?

What have you tried so far?
Usual options:
- Moving front fins back
- Back fins forward
- Mast foot back
- Straps back

Forceful style does not sound good for lightweights ,one of those boards that would be riding you .

I have the 2020 Cube 87, 2020 Cube 98 L and a Severne Pyro 105 L at home, a 2016 Cube 95 L in South Africa for Christmas holidays, and a 2020 Cube 106 L in Puerto Rico for long weekend trips. I ride all of them as a twin in cross on and quads in cross or cross off. The Cubes are absolutely brilliant boards. The Pyro is a great board, but for me the Cube has something special.

I ride front strap in front hole, back strap in back hole for cross and cross off, and one further forward for cross on. Mast base is always behind the middle of the mast track. For quad I use the stock MFC front fins and K4 incinerator rear. For twin I use Black Project Epic Wave. The stock MFC rear fins were very meh, tossing them away was an instant performance upgrade. For quads rear fins I go slightly smaller than stock fins and for twins I go quite big. For reference I weigh 90 kg.

Fin size wise, for 106 L I use 17.5 Black Project fins for twin, and K4 incinerator 16 cm rears. I think the stock MFC rears were 16.5 and very wide, so a lot more area than the K4s. For 98 L I use 16.5 cm for twins and for quad rears I use 15.5 cm K4 Incinerator.
