Replying to New skis are hard to turn

I just tried out my new tom wallisch pro skis the other day. They got a preseason "tune" so I'm assuming the shop did some modifications to the edge bevels from what comes out of the box. For some reason, they are hard to initiate and release when turning. I felt like I had very little control over my skis. It is very possible that I am just used to dull park ski edges that skid and manoeuver really easy without catching, but I was struggling a lot more than usual.

Is this just a lack of detuning contact points or what? I have heard that line park skis usually turn really well, so I was confused and troubled. After a few runs I went back to the car and grabbed my old skis because I felt much safer with them. I have done demo days with a variety of skis, but I never felt this uncomfortable with a pair of skis. Granted, the conditions were very firm with that granular / sandy / shaved ice on top.
