What about the Stockli XXL? You can pick up a pair for about $500. Not cheap but its a good bump ski and on piste plus decent crud buster as well.
It not really for me because of my size (260 lbs) the iso core feels too soft but if your lighter it may not be bad.
I just picked up a pair of the 2007 Stockli snake pop twin tip for soft snow and bumps but I won't be using it on groomers except maybe back to the lifts. It was $320 so Its not too big a risk. Plus, you said you want on piste performer as well.
I'm a bit of a stockli fanboy (both because I love their skis and at my size they have a good selection) so I can't really comment on some of the other skis. But, perhaps you could post you size.
