Find a pair of Kenjas the same length and compare. Often it's 1 cm forward, not sure about these. I had my 177 Auras mounted like 177 Mantras: we moved the bindings 1 cm back after lining them up. That was a long time ago, though.
I would suggest the same, if you can put both skis on the bench and measure the suggested mounting points that will reveal a lot. Also if you have a
similar ski in shape and length you own that you like, you could compare that mounting point as well.
I would only add that if you have small foot- 21 or 22 size boot, maybe even 1.5-2 cm's forward, though again other variables come into play-
typically more hard snow oriented, a little more forward, more soft snow oriented, a little back.
Since I am a little old school, I tend to focus on the location of the toe piece, and the ball of foot location more than boot center, especially when looking at
boots on either end of the size spectrum.
