I have a Naish Hockua x32 length 9.1

It came with a Tri fin setup, I am keen to try a quad setup as I hear it is faster and looser in this setup.
But... I don't feel like wasting the money on new fins, if it isn't going to make any difference.

Could I use the quad fins from my 7.6 quad surfboard ? Or do I need to get specialised SUP fins ?

I generally surf small 1-3 foot waves max on the sup.

Thanks
