Replying to Problem with a ski shop mounting

Alright so I got a new pair of AR5's and rossi axials and had my local ski shop mount them (perfect center). So I come back the next week they look like they did a good job so I go home.

I notice when I get home that one ski is mounted a little farther back then the other. My right ski is mounted perfect center and the other one is probably 1/2 an inch or less behind that.

So my question is do I take them back and have them remounted or just leave them? I dont think it will make a huge difference, but if anyone could give opinions that would be awesome. Thanks in advance
