i have had mine set to 15 and -15 all along. it just seems like it would be weird ridding my board any other way. It works fine when i freeride down a slope carving, and just seems natural to me. I also go into switch a lot freeriding down a slope, when doing 1s and nose press 1s, etc. so its awesome having it set that way. I guess its personal preference, but personally, even if i wasn't riding switch, i would still like to have it in the 15 -15 stance, but thats just me.
