Anyone had a chance to try these ?

I haven't. ... but i am very familiar with their G10 and carbon windsurf fins. Given their other constructions and the description on the link you posted, i think they would be a far higher quality than many of the surf fin companies' offerings.

I have a set of large Flow's on my Infinity BlurrV2 (8'5").

Honestly, I can't tell a difference from the stock Infinity fins and the templates are very similar. Granted the Infinity fins were pretty high quality to begin with. Any benefit they may impart is probably lost on me. Half the time I couldn't tell between running quads and thruster on my surfboards LOL.

They are a touch lighter and look cool which is the most important thing!

They are well made and so far have resisted any chips or nicks.

Not the most informative review - sorry!

Most importantly they match the colour of your board

In my experience, this is the case with most "classic" fins.
It is very hard to tell the difference between fins of the same dimensions.

This is why you should first try really different fins first (Quobba, C-Drive, Starfin, ...) to "educate" your feelings and experience clearly the different possibilities fins can give. Then, you can perceive them in classic fins.

Otherwise you will just waste money buying fins for nothing, and fall victim of "hallucinations", finding differences where none exist.
I had discussions with people having only tried classic fins who were certain that they surf-prone-paddled faster with some fins...
and even with somebody who thought he was an expert on fins because he had been a vendor in a surf shop and tried many fins... but he only tried the mainstream fcs and future ones... he made a perfect example of the Dunning-Krueger effect :-)

It is the same with music: once you listen to solo instruments, you are able to recognize them in music.
And also the same with wine and food tasting.

I surf mostly 3 boards with 2 having classic fins and one with Quobbas. That board feels like it is on rollers. Quite a clear difference.
