Randall,
Welcome to Real Skiers, and, enjoy your powder. I am an eastern skier and it's been very warm and limited skiing.
I'm lighter by 20 lbs, and own the Kastle MX88, in 178, and agree with all the great reviews the ski gets as a front side carver. It shines in hard eastern snow, and, worked great in some warmer Summit Co. snow late last season. I know the Rossi 88 is getting good reviews, I hope to demo at a local demo day in a few weeks.. Here's my take. There is a several hundred dollar difference between the Kastle and Rossi, and, I would have to be blown away by the Kastle to justify spending those $$$$ on a ski that I would not use as a daily driver. My read of the 88 reviews is that there are several, including Blizzard and Head, in addition to your 3, and all get solid reviews. Then again, if the Nordica made you smile, why look any further? The 88 class ski is differentiated from each other by small features, not sure you would need the best hard snow carver.
( I did get my Kastle as a demo via a Kastle rep - would not own it for full price as I hate depreciation.)
