Mounting point on 2010 line chronic cryptonites

The other day i bought a pair of chronic cryptonites and i got them mounted at mid sole/recomended without putting much thought into it first. but when i picked them up they looked like there mounted pretty far back from what im used to. (the midsole is 58mm/5.8cm back from center) I bouth the skis for both park and all mountain, so does anyone know if the point on these skis would perform better if mounted about +2 for some spinning and rails and also groomers and pow? If anyone has ridden them at midsole tell me how they felt to you.
