does this boot come with multiple tongues that can be interchanged to adjust the boots flex/stiffness? I've been skiing the Krypton Cross for the past 4 years and the fit is perfect but they seem like they are a bit soft. Don't get me wrong, I LOVE the way they ski but when I get into the crud/big terrain I find myself clamping the buckles down all the way and they still seem a bit soft. I am 5'8" 170, aggressive ex racer. I want a boot that can hold up but I also like my boot to have good flex. I just don't want to drop $700 on a new boot and find out that it is too stiff and unresponsive. I know that these boots can be adjusted in multiple ways...but in all honesty, how soft can these boots actually be after making the proper adjustments? How stiff?

I wonder if I could modify my Krypton Cross boots with a new stiffer tongue? any other suggestions for making the Crosses stiffer?
