Different skis designate mounting points differently. Where is true center on these skis? Is the "team" line true center? What I mean by true center is the midpoint of the ski if you pull a tape measure from tip to tail. Based on my experience, if you like the ski to pivot on a dime, mount them at true center since this will be the balance point of that ski. You'll probably get more tail on the ski at this mount point which is good for landings. The compromise that you make here is that you'll have less shovel in case you want to charge However, less shovel makes it easier to direct the ski in tight spaces. Usually manufacturers will designate this mount point as their recommended line for park and pipe applications. However, in my experience, I like the fact that they're easy to pivot in tight trees. My S7s are mounted at this point (+3 on the S7) and they're my go to pair in MRG woods.
If you intend to ski them in powder, keep them mounted behind true center.
