You should come to Bachelor-we have all 3! The Mag 8 is a heavier-feeling wood core ski, the AMC73 is a lighter air-carbon core ski-feels distintictively lighter underfoot. The Apache X is a wood core ski. The Mag 8 also has a tighter turn radius, the AMC73 and Apache X more of a traditional midfat construction. The Mag 8 is a little snappier than the Apache X, which runs a little more on the damp side (it also has the larger turn radius). All 3 are great skis. Typically, the Mag 8 in 168 feels a little more substantial than the AMC 73 in 170, and the equivalent length in the Apache X is 174. All are good choices.
