Why people bother so much about what kind of board someone sail? Sail whatever you want. If you wnat to sail a formula board in 800kts, that's fine. If you like slalon boards in 10kts, that's fine too. If you like wave boards more than other boards, that's ok.
The important thing here is to be on the water and have fun whatever board you sail.
Peace, good winds, happy new year for everyone, wave sailors, formula sailors, slalon sailors, freestyle sailors, all sailors in all kind of sailcrafts all over the world.
