That make a lot more sense than the camber being limited to between the bindings (where it could not be compressed by rider weight and would offer little benefit). The sizing on your 159 is a solid fit for your specs. I think you are going to adjust nicely to this board and will end up enjoying it a lot. Camber has its benefits (energy, edge hold and responsiveness to name a few) but there is an adjustment period. Stoked to hear what you think in a couple of weeks!
