I struggled to adapt at first but it went better and better. It's impressive how we find a recovery at the bottom and on certain tricks. I noticed that gaining speed was much easier.

Surfing for at least 6 months now exclusively with your DYNAMIC FYN. Being well positioned on the surfboard provide a gliding sensation that I particularly like. I would like to congratulate you for your involvement in this project and to encourage you continue to develop this concept.

I loved it they are so cool! Hyper reactive tail. Even for big and hollow waves, it rocks!
