Kinda curious where the other 10% of your skiing time went...*raises one eyebrow*
And I'm going to say that (depending on the year) the Elizabeth probably isn't going to be softer than your ARVs, in fact, upon hand flexing both in a shop, the ARV was noticeably softer in the nose, and, if I remember right, softer in the tail as well.
I'd suggest getting the new Salomon binding, the STH 12, available here:

That one only has the 100mm brake, but Salomon brakes are very easy to bend out, and if you really want, I'm sure they'd sell you a wider one.
