I just got the 2011 Armada Halo 176 and dont really know where to mount them. if im gonna ski mostly park and a little pow, should i mount them center or factory recommended?
Factory recommended is there for a reason, it's where you're supposed to mount your ski based on the manufacturer's design.
That being said, I don't know exactly where that ski's recommended mounting is, but I can tell you that if you're going to be doing any amount of pow you'll probably want it either at recommended or maybe forward a "tad" for park.
