The boards I use the most are the isonic 125 and futura 101. Really love those two shapes, to my opinion the 125 is one of the best SB shapes of the past years. (have also tried sonic 125, isonic 122 2007 and 2008, but didn't find them better than the 125 isonic, so did not change the 125).
The Formula 155 I do not use much, due to its length its great in planing early with a 10 m during the summertime. When the wind picks up, I get on isonic 125 and 8.4 RsSlalom - great!
The futura 101 indeed is also a great shape, especially with 7.8-7.2-6.2. Maybe the upwind performance could be better - I've heard the 2009 101 does this job better due to slightly sharper rail.
But in really overpowered 6.2 conditions, the F101 gets to big due to its width of 65 cms.
I've been told that the sonic 85 is more relaxed to sail compared to the isonic 87. To your opinion, is that true?
