Hi guys, I'm seeking for some advice looking for some fins for my Evoke 8'6 sup I'm 100kg. Any recommendations on either quad or thruster setup?

It depends on what you want:
- control and be able to tighten your turns: thruster
- faster but more drawn out turns: quad

This said, I recommend the Quobba fins in a thruster setup. With their added speed and hold, you get the best of both world.... and you will not want any other fins once you try them.
I use the M (orange) on my 8'4" 120l (I am 100kg) as they provide enough hold at speed. But if you tend to surf at lower speed, you'll want to wait some days for the L (black) to be available. I use the L on my small wave boards.

To rephrase Colas comment -- more vertical surfing with power --- thruster
more carving surfing with speed --- quad


So depends on your local fav break - point - beach - reef - rivermouth?

I'd add that for the quad setup, SUPs seem to work better with very small rears. Much smaller than the ones recommended for prone surfboards.

Agree Colas. I found that my Sunova board came with a smaller rear in its thruster set up which surprised me at first.
But now I know that it helps tighten my turns due to more slip at the tail end with the holding power of the larger front fins to assist with control.
Why did the Sunova owner Bert Burger do it that way? Because he knows his stuff.
I also heard from a mate of mine that fins like the C drive fins are great too. Colas knows all about them too.

Yes, note that the excellent classic Al Merrick thruster set always had a smaller center fin. As the Harley Ingleby, even though designed for longboards.
Since you can mix and match FCS sets when buying them, I tend to buy larger fronts than rear. For instance, the lastest 5-fins set I bought was the Jason Stevenson on,e but I bought the sides in L and the rears (quad + central) in M

And this is what I use in my small wave board with the Quobba: L side + M center:
