If it were me, I’d center them.
It’s more fine tuning talk, I guess, but, I have found the skinnier I try and make the skiis with the bushings, it does exactly what you described. And then when you make a turn with your skiis, with no lean, just a flat turn, you will see that ski position on the ground get more exagerated. Almost like walking on the sides of your feet depending which way you are turning.
Now put that same thought in soft snow and a slope on a hill and make a turn or go across that hill, the down hill ski will dive some. This makes it harder to get the sled balanced into the hill and weighted to do your maneuver or turn. Its not always a big deal but sometimes its just something that makes you muscle the machine a bit more. Or, if you need to get aggressive and turn on that slope or hill, the ski dive will make that critical turn harder, or another way of putting it, more energy to needed to make that turn. Most of the time its in slow speed situations. The earlier Cat skiis did this more also.
So, the dive isn’t completely eliminated by centering, but the stance sure seems more squared up.
