Christine said some really good things about the 86slim for super high wind/ really rough condition days in the French Forum. Maybe this might be more appropriate for you as from what I've gathered you're obviously not on speedcourse tight water, and the 86 slim was design to be a high wind/high control slalom board.
Maybe the team would advise differently. But I also asked about these boards a while back because I'm super light (55kgs) and could use most of them for even medium days. I think the conclusion was that because these boards were designed solely for speed, they lost out on jibing ability.
Let me know if you want a translation of what Christine said.
