I've also noticed that the not only does the stiffness improve my skiing but the height of the boot. I feel as if my fulltilts even with a 10 tongue will be like wearing low profile sneakers for basketball when I could be wearing hightops. I know I need to go to a boot fitter, but these were such a hot deal I couldn't pass up. I just need to ski the rossis more than 1 day to really see how I like them and then decide what to do.
I must say though that when I first thought about a 130 flex boot I was timid to say the least thinking it would be sooooo stiff but it really isn't that bad and helps me control my skis a shit ton better.
