Replying to Using Lightweight boots for everything?

So, my boots are dead. (Scabby old Salomon alpine boots from like 9 years ago)

I'm off to buy new boots in the sales...but I figured.

I want boots for backcountry, maybe touring. SO why buy alpine boots.

My worry is that if I went looking for something mega light along the lines of these:

Would they be too pussy and soft for all the day to day piste stuff?

I was thinking more along the lines of:

would be more flexible.

I guess I'm looking for suggestions as to what folks are using to cover all bases if they want one boot to rule them all.

If the superlight ski/running guys would do the job, why would I lug heavy guys about.

Open to suggestions & ridicule.
