I guess you've seen the snowy Scarp in this BPL thread ? Supposedly stood up OK in that snow...
and here
I haven't used my crossing poles yet, but it's been good in wind without them.
I haven't camped in 'proper' snow for a few years anyhow 
I think Henry would make a killing in Europe if he designed a Scarp type tent with the basic features of the Laser Comp/Akto/Power Lizard etc. allied with the cut and end struts of the Scarp
i.e. Dark Green, one door/porch so allowing weight nearer 1kg rather than 1.5kg .(ditch the crossing poles facility on this edition) . It's a '1.5 man' at the moment - reducing the size a little to make it a '1 man' would allowweight reduction...
