Normally I would just mount at recommend and not worry about it, but the recommend mount seems really far back on the Gotamas. I also worry because the only other full rocker ski I own is the k2 hellbent and I prefer my hellbents mounted at +3 (they had schizo's on them so I was able to try a variety of mount points).
The Gotamas are definitely more directional than the hellbents though, so there's that to consider. Also is the "volkl reference" at core center? The only markings are volkl reference and +1 and +2.
