My 2 cents.

First of all I have not skied any of these skis so my input is based on how I would think this through for myself.  If I already had a good 95 under foot and wanted a second ski, and I like moguls, I would go for something that was good in moguls. Of the skis that you mentioned, the 78's are the only ones on the full site that got a moguls rating.  The Nordica's are 84 under foot and the 82s aren't a particularly good moguls ski. (known more for great GS turns, going fast and crud monsters).  The 78's give you the biggest difference in width and should be the quickest.

Depending on how much you like moguls, you may also consider even a narrower ski, kind of a front side/backside combo.  For Fergie, I understand why you would want some width.  From what I have read, the 78's are hard to beat for what you are looking for.

I would also encourage you to consider waiting so that you can Demo.  That way any length considerations could be sorted out on the snow.

There are some good reviews on the epic site.  Here is one, there are others by dogcatching who does great reviews.
