well, that depends almost exclusively on how stiff of a boot you like. i ride the rampages for everything, but i only weigh 160lbs, so with the flex blocks in, the boot is plenty stiff enough for me for skiing steeper, sketchier stuff, whereas with them out, the flex is nice for park. given the option, if you like a softer boot for riding park, get the cross. it has all the same features as the rampage, but with a better liner. the pro has a stiffer tongue, and again, a better liner, but it basically comes down to flex, because beyond that and the liner, there's not much difference between the models. you can reverse the toe buckle on the cross if you want, but i flipped mine on my rampages cause they always pop open in the reverse position.
