I went from a Hex to a Flux, the fit's quite similiar.
I really liked my Flux, but kind of despite itself... They're massive, and not light, and the strap mechanism isn't brilliant. And the damn fool spoiler, grr (it does come off)
But- it was comfy, cool, had excellent coverage, and sat so well on my head- it's a cliche but it went round my head not on it, the HEx was always "on top". So stable with a light, too. So miles from perfect but the good stuff was so good I don't care.
Fox's Striker is also excellent- a bit more XC, it weighs miles less, fits similiarly, and is a wee bit cooler but does have slightly less protection at the back of the skull (it's still better than a Hex for that, mind, but it's not as burly as the Flux) And just generally better executed- smaller, better straps, etc.
