My Driver X boots are stiffer (and MUCH lighter) than my old Raichle hardboots. I love em. For carving I use Ride SPI bindings. Inexpensive, comfortable, stiff highback, and enough cushon for those carve - to - drop-off situations. Not as adjustable as the Catek's, but it doesn't really bother me any. I like the convertible rubber toe strap, which I use the old-school over-the-top way. I find the toe caps like the Burtons are great for cinching your foot back into the binding, but they add to what's hanging over the toe-side edge..... my feet are big enough as they are.
