Previously always confirmed the fin was set to bone stock. Then found my happy place in boot position. Next change was 2-3 years later when new ski arrived. Then starting 1 year ago with the Radar 2016 Vapor, the knowledge base shared by so many others on this ski on BOS, and the publishing by @SkiJay of the Fin Whispering rosetta stone, I got comfortable changing things up. Just a few weeks ago I flipped from the long and shallow settings to the short and deep. Felt very similar but better in little ways.
