I had my 163 cm MX 83s mounted .75 cm forward after reading some posts on this site. The skis felt really short so I moved the bindings .75 cm back. It was quite easy since they're on a short plate or track. It helped but they still feel short so I just moved them another .3 cm backward. The bindings are now close to the back of the plate. I.e. the bindings may be centered properly on the ski but the plates are forward. And the bindings are not centered on the plates.
Is this OK/safe? Did I really do anything? In other words do the forces get transmitted to the ski based on plate position or binding position or some combination of these factors?
As an aside I find this a little annoying; it's a great ski but those 10 cm intervals are killing me. At 5'6" and 140 lbs a 166-168 would be ideal in this ski. 173 just seemed like too much too ski.
Willing to get those plates moved back if needed.
