Best binding for the new Karhu Mountain XCD with Garmont Excursion boot

Howdy folks. Having some trouble trying to find the binding I dream
of to complete this setup.

I have a pair of Karhu Mountain XCD's in a 185cm and a pair of
Excursion's (Padlock) on the way. I got a decent deal on the padlock
version, I am hoping I will find them close to the comfort of g-fit
liner. Anybody tried both yet?

I am thinking the Voile 3-pin Cable binding is the way to go since you
can take off the cable for extended touring. Are there any lighter
weight bindings out there that might be a good fit inbetween these new
backcountry skis and the Garmont Excursion (that claims it has been
made for these types of skis). I am wonderin' if they plan to design a
lighterweight cable binding now..
