Replying to How many times can you mount skis?

My ON3P Kartels have been drilled 3 times already and the spot they're mounted in right now sucks. It's been a rough go between shops and bindings - first shop couldn't figure out how to mount my Tyrolia Adrenaline bindings after drilling holes, so they bought me Marker F12 Tour bindings and mounted them forward of where I originally wanted which I said okay to rather than demand new skis. My mistake. Half a season goes by and these bindings start pre-releasing and won't hold forward pressure. I still have the Tyrolias, so I take them to another shop who knows how to mount them, but I fucked up again and didn't specify that I wanted them mounted behind the old holes, and so they mounted them in front about at -1. So now my skis are nearly center mounted, and they won't float in powder or hold an edge without skiing hard in the back seat, and they've been drilled 3 times. Is it possible to try to mount them a fourth time behind all the old holes at -4 or -5, or do I need to just start over and get new skis?
