Help-Should I use Solly 912 ti or Dukes

I am getting new Bros soon (hint Pat;) ), and am not sure what to mount on them. I have a slightly used set of 912 Ti's which are nice and light, or should I slap on some Dukes? I have a touring set up already (Teledaddies w/ freerides), but Bros w/ Dukes would be handy for traveling and occasional side country touring.

My biggest question is how big of a weight penalty is there with the Dukes, and will I notice it for Alpine use. I don't need a DIN higher the 12, so that is not a major factor.

This will be my everyday resort ski.

Thanks one and all.
