Depends on the ski imo. A ski with a symmetrical sidecut will behave fine, because you will have the narrowest point of the ski under foot, and it will be easier to initiate edge and flex the ski in a carve. I also recommend that you very clearly explain, and if you can, have a shop tech measure the ski so you know exactly where your bindings will be mounted. Personally, I have a pair of head caddys, center mounted and a pair of 2016 BDogs, .5cm behind center. If it helps, I'd be able to ski gates in a GS course on my Heads if they had sharp edges, but again, they are mounted pretty close to their sidecut center. If you're unsure, I'd recommend you go 1-2cm behind true center. There are many other factors that trained ski techs will know more about but that's my basic understanding of mount points.
