i use tecnica race 110's for that. they have a low flex index on them but they are surprisingly stiff, i used to use 130's but i decided to go down so i could use these boots for everything and i don't feel that huge a difference, i only weigh 160 lbs but i ski aggressively. i don't like super stiff boots for racing and these are perfect for the freeriding i do which is mainly steeps, pow and cliffs, they have a nice absorption in the tongue but they're stiff enough to control fat, long skis at high speeds. a little stiff for park but if you're used to stiff boots they're fine. so i use them for exactly what you do and they hold up great, my favorite all around boot. and no shin bang for me on these and the feet are nice and cushioned but if you have problems booster straps work like a charm, i'm considering maybe getting a pair although the powerstraps on the 110's are pretty beefy
