Surfing Waves

I'm searching for Futures Fins to match my Hypto Krypto 6'4 Thruster setup. I'm a 94kg/204lbs intermediate surfer who is looking for speed but also for a loose and skatey feel in the turns. I will mostly surf in Norway 3-7ft waves.
So far I came across the Techflex AM2 vs Matt Biolos MB2 vs AM2 Honeycomb Hexcore.

Has anyone experience with the above ones or an idea what would be the best?
Thanks in advance

Have a look at the HS2 it may suit, Tromso or around Stavanger?
Unfortunately not a lot of option to try at the local surf shop there.
The recommended fins are HS1 Honeycomb if you have those fins already go a little smaller and smaller.
Good luck and warm wetsuits
