I've been using these fins in size large for the past several years, and they've become my go-to for many of my boards. I've been using them since the previous blue colorway, and continue to use them now in this red set as well.
These fins are an awesome choice as a neutral, do it all template. This especially becomes true on boards with 5-fin setups, as they are super drivey and pivot well into sharp turns when run as a quad. Likewise, they have enough rake that when you're surfing an open faced wave, these fins will keep your board on rail during a hard drawn-out cutback or a deep bottom turn.
I enjoy the stiffness of the performance carbon construction as well. They feel light yet locked in, and always feel stable at high-speeds in big surf. On the flipside, that might be my one drawback of these fins, is that I sometimes wish there was a little more flex/pop out of them in smaller waves, especially when running them as quads.
Overall, I have had a ton of fun with these fins on boards from the RNF Redux to narrow, low volume HP shortboards, and even on stepups. They are a great do-it-all 5 fin set, and their durability has been amazing as well.
