Replying to Sketchy steep ice Touring ski ( with a sprinkle of shit pow)

First off heres some info about me

LOCATION: New Zealand (North Island)
HEIGHT/AGE/WEIGHT: 6ft 22yo 65kg
ABILITY LEVEL: ExPeRt
BUDGET: open at this stage
WHAT KIND OF SKI DO YOU WANT: Light touring ski to handle steep icey terrain mostly

Looking for a freeride toruing ski that will shred ice/refreeze/crud/slush and a sprinkle of wind affected pow.
I ski hard and fast but I dont have very strong legs (blown knees) so a lighter ski is preferred. Something that will handle shitty heavy pow and ice (One ski quiver type ski) must come in big sizes (185+). Decent rocker for that crud and refreeze but as much edge contact as possible for the ice and nice long turn radius so i dont trampoline too much on steep sketchy terrrain.

Ive looked at a few ski's. The J skis slacker sounds good but worried that 110 waist wont hold up on the constant ice we get
