Performance Core
Performance Core (PC) fins are made using a multi-layered resin transfer molding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light, and can be used in a variety of different conditions.

These are the best fins ever made however, if they came in large, I would definitely buy a set. Yew!
Perfect amount of hold and release when I wanna slide the tail. I'm 135lbs and these fins are a bit looser then the mediums but still have the drive and hold through carves.
AIM tri is the best fins set i have ever tested. Could easly notice more speed and control by using Lost Uber Drive. So far, as well in my Snapy WC model the set of AIM brought some improve and a feeling of more sharp executions trhough the ride.
I've found the template of these fins to be the best all round. I use these fins on a variety of boards for a fish to a Longboard.
I put these fins in my Pyzel Phantom round tail and the board really lit up 🔥
Heaps of drive with plenty of release too…..perfect combo….best fins I’ve ever had 🤙🙏
