I have a Flux 168 and a Contra 167. They are both very capable carvers that are quite at home off the groomed as well.
I find the Flux to be the smoother carver, and the Contra to be grippier and more aggressive. They can both handle everything from super firm to soft groomers. I tend to favor the Coiler on steeper terrain, bad grooming, and really firm snow… and the Flux on mellower terrain, colder snow, and when I feel like taking laps through the (smaller, I’m getting old) jumps.
Off groomed I find the Coiler to generally perform better… it requires less input … but the Flux has been very damage resistant (thicker core since non-metal, Durasurf base) so I choose it anytime coverage is questionable or when riding unfamiliar terrain.
Hope that helps
