These bindings are awesome. I have been riding CO2s for years but switched to the Union Force SL last season because it was lighter with a better flex and just as much response as the CO2s.Now the Force SLs are going in the closet. The Prophecy is so smooth and responsive and the reflex design does give you better board feel and pop, if you can't feel it then there's probably a lot of things you're not tuned into. The flex is as advertised "medium" just a little smoother than the Force SL but I found they were more responsive when paired with my Burton boots because the fit was flawless.Prophecy and Ion is park/all mountain nirvana. (Not too soft unless you are someone who makes heel turns by hammering your highbacks).
