Any reason you don't want to use the Genesis?
Not particularly. I bought them based on the "tech" and some positive reviews (they match my board color scheme, too, which helped). I haven't used them yet, but they DO feel "different" with that articulated hammock in the highback (at least strapped in the carpet). Almost "flimsy". I bought them through Dogfunk/Backcountry, so if I hate them I can always return them. But I don't hear a lot of chatter about Flux and a lot of shops I've visited tend to try and steer me to Union/Burton (they tend to skip over Rome, Ride, Flux, K2). I really like the Burton buckles, but the Flux seemed even smoother. If I hate the Genesis, I'd probably step into the SF45 or some Cartels.
