WWMD, What to mount dukes on?

I have picked up several different binding sets and skis and I am still trying to put the puzzle pieces together.

What I have to work with:
189 B-squads currently mounted with ZRS

Districts unmounted

195 Praxis unmounted (not here yet...)

Marker dukes

Fritschi freerides (white ones)

Solly 916's

Rossey fks 155 ($25 at cochran's ski swap!)

I was thinking of putting the dukes on the squads, 916's on the praxis, and freerides on the districts.

I am just trying to figure out if it will be worth it to have the bomber sidecountry rig that will be like touring with a cinderblock on each foot. I know I will be very very happy on the downhill, but with dalbello KR pro's it will not exactly be a rando racing rig. Will the high stack height of the dukes make me wish I still had the ZRS's? I have seen people mounting dukes on praxis but I don't know if that would make sense for EC gnar. I am also wondering if praxis/916's and squads with dukes would be the right jackson trip setup or of there might be a better combination. Ideally I would bring the districts, praxis, and squads out west but I doubt that would make weight.

I would apeciate if anyone has any other ideas on how to piece everything together and what to bring out west.

Just as background I have a nx21/180CMH rig and some 196 RR XXX's with 916's too.

Thanks

Well you could do that, or put the dukes on the praxis, or you could buy another ski altogether. I would guess that you want to keep the freerides on the districts though. But IMHO, I would pick up another ski. Just my .02$.
