My BSL is 317, the small Duke fits up to a 325mm BSL. The large Duke obviously will fit my boots as well, I'd me more in the middle of the range. I've read places that say you should be in the smallest bindings you can be in because of weight etc. Is there any draw back to being right at the edge? Other than I couldn't loan them to people with larger boots or whatever else, not really worried about that just considering performance.
Thanks in advance
