Replying to Where should I mount my Line Prophet 98s?

5'11" 210lbs and ski all mountain.  Mostly groomers and off piste, very few park runs (have park skis anyways)

I was just wondering if I should mount them at the midsole mark located on the ski or -2cm back or anything else? Reason why I ask is in the past I have brought skis to get mounted at my local shop assuming they would mount them correctly, but they always seemed to mount them too far back.

Where should I mount my LP 98s for all mountain?
