I think Formula One or Moto GP tyres are the equivalent to our fins! The fin is critical and can make the difference to winning races or not. I use Chopper Fins from Ludovic Jossin and am really happy with the big and medium fins and the small ones should be really good for Fuerteventura. In the Canaries you need a fin that will keep your board down in the water but that is also really fast. We all use production equipment so the fin is the only piece you can change. It is the place where you can score an advantage. I spend between 3-4000 euros each winter on fins. You always want to have the latest fins just to test in case they are faster than what you have. You can’t afford to miss anything on the market. Sometimes a new fin can be useless but you need to know how they perform. The cost is going to be even bigger with the foils now! I don’t normally train with my best fins, but now I am trying to have my best ones in double so I can have that sensation while I am training. I will keep my best ones just for the race. My best fins come out like a new tyre! On the beach they are always in the cover, I race on them and when the day is over they come out of the board and get packed away. I am scared to have my fins stolen. If somebody stole my car or van, my fins would be the item I would be most scared to lose. Some fins you need to wait for years to replace.
