I am pretty clueless on fins in general, but on my 9'4 and 9'1 Acid, I like the FCS MF-1's

I weighed 107 kg when riding those fins, they loosened up the board but had plenty of drive.

In stock Sunov Fins, I run the 94's in my Acids

Hey, I have the 8'10 Acid 120L and used a few different fins on it @85kg. The stock fins are really big so I started playing around with the fins and got some FCS Nexus H-3 fins (large) and wow are they the perfect fit for the board! I had hoped the FCS Nexus H-3 fins would live up to their hype as they seem to be either loved or loathed by surfers in the reviews. I got some nice waves and the board just cuts through the wave like er...acid! The fins have great grip and release and very smooth and also snappy off the top. The large FCS Nexus H-3 fins are a lot smaller than the stock Sunova '102' glass fin which are quite big.
UNTIL...
I got a set of Maui Fin Co Kai v2 thruster large surf fins (not SUP fins). OMG...These carbon things are next level performance and I've tried a lot of fins! Faster, more acceleration, snappy, much tighter turning with grip and release like nothing else! I should try the FCS Nexus H3 again but these Kai V2 let me do turns I have never done before on the Acid!

Thanks for the feedback. The Acid is a wicked board so I wanted to give it a proper review. I think the thing to consider is that the Acid works very very well with other fin brands and don't be afraid of going smaller. I am a fin fanatic and pretty much always swap out the stock fins for other brands that suit my interest and conditions. This can be an expensive hobby but when you strike the right fin set up it can transform your riding experience. So for me the MFC Kai Thruster V2 is a joy.

I was thinking medium too ...but haven't ridden a thruster for 1 year..because I've gone a thruster set up only on the acid ,I may need the large ..( been riding a flow with quads ). what about these .i've alway gone after market fins ,I find you get more speed and turning .can't seem to locate any of your ones pictured ,at my local store .these look cool. And in stock .

I quickly replaced the Sunova 105's that came with my "Creek" with a set of fins from Rob Piros.
(I detected that Rick thought I was a bit soft using such big fins)
I had to buy a fixed centre fin to match the sidebites that I had, but that was ok.
They have made a big difference - people think I can actually surf!
Anyway, I notice that Rob's website says he is sold out of the sets - maybe we can hit him up to get another run done?

totes agree. love these fins VP!
I use the v6 sides in my sunova style 10 footer and v8 in rear.
if i had them in fcs, id go v8 sides and v6 rear in my sunova flow.
I use the v8 sides in my 5'11 funboard which also gives it heaps of drive for getting up quick and getting down the line in our close-out summers.
do more piros and ill prob buy a few sets in fcs and future. ps even fcsII you shud do! ill go a trifecta.

Where did you buy the "Maui Fin Co Kai v2 thruster large". I have been clicking all over the place, down one dead end after another...

I'm in the same boat - 8'8" JL Supertech with the stock thruster setup. Tried it as a quad once and didn't like it (although I may give it one more shot).

I've ridden the GL2 Lopez in a quad setup and liked those, thinking about switching it up on the SuperTech, any suggestions?

I have not had a chance to try my C-Drive fins on my Acid yet - but will try this weekend and report back.....If they have the same impact as they have had on my Starby Airborn.......

I'll be surfing like an animal tomorrow with new 3 d fins on my 8.7 flow .

Thanks guy ,will check it out ...I find the stock fins fine at the moment ,but will try it with no rear as well ..
I have ordered some large FCC 7.0 FCS carbon core fins to try .maybe squirt a bit more out of it .

The acid is pretty loose as is .great board .it really delivers .

the leopard s look wild .tardy.thanks everyone else .
