Wow, excellent feedback from all of you - I ordered the flux with their standard build, relying on the expertise of Thedo Remmelink and Sean - I told him my weight, not sure if it influenced the decision making process of board build tho - I'm happy to see all the feedback. Bottom line looks like it'll be a safe bet to go with the 8, as it's the right blend of ride all day / stiffness compromise. I want something that I can still olley well, since my last board was a Jones MTN twin - this new order is my first of transition into carving.
I believe this is standard flex - Ryan Knapton on Flux - beautiful fluid and smooth carves
