I would prefer Demon 2 hubs, ideally 15mm front and 12 x 142mm rear. I'm told they can be adapted so 20mm and qr 135mm will do.
I'll buy a pair of wheels (depending on price) but I'm building 29er no-tubes wheels so it doesn't matter if it's just hubs. Email in profile.
I think Cube specced coloured Demon 2 hubs on their Stereo so should be a few sets around!
