Mike Dwrote a review of Moment Bibby Pro Special Ski on March 19, 2012
About me: 5'8" and 145 pounds. Aggressive skier. Riding the 196 mounted at +1.5 from recommended. Have the tips detuned (highly advise this).
Quick sidenote:don't buy these unless you go fast. They are pretty dead feeling at slow and moderate speeds.
The stiff tails have saved me on some off-balance landings that I could never have recovered from on my hellbents. They bust through chop like there's no tomorrow if you're willing to charge, and you will be. The edge hold is shockingly good on firm snow but breaks free predictably.
A couple of notes on the specs:backcountry (and Moment, for that matter) has the dimesions listed as 150-116-123. My skis are labeled 150-118-128. I find that odd. I'd also debate the "rockered tail." I disagree with that description but maybe that's more of an issue with my definition of rocker than anything else.
TL;DR:Want to charge and don't ride switch? These will treat you well.
