It's kind of funny to read this actually. A year ago the 161 was considered too difficult to sail, too AA like, demanded a strong rider etc etc. Now everyone is praising the board which they abandoned a year ago ? Make up your minds.
But IMO it's interesting to see a board performing well in certain conditions, and in others a different board has the advantage. Look at the latest F2, the big Z, clearly favored in the light winds at the Euro's but when the wind picked up the SB's were favored. Same seems to be the case at the World's in Portimao, in the lighter conditions the Z and SB 162 had an advantage.
