I thought only the quality of the board, not the performance of these boards. My friends from the Croatian had problems with isonic 2010, because on top of the boards started to appear small straight cracks and then entered the sea in the board. All these boards have been under warranty and the dealer receive all the new boards. Now I buy the same kind of board, which has passed the warranty period and I'm afraid that we do not break.
But it does not matter, I guess everything will be ok. I know the fix these problems, so if it happens, we will fix it. I drove isonica 121 with a 7.8 sail and the board is so easy and so fast that I immediately fell in love with isonic. I have just bought a slightly larger sail for the summer and slightly lower isonic for the winter. Greetings from Croatian!
