Im sure more recommendations will come but here's a couple for now.
Last year Salomon 22. Nice allmnt/park ski. Rockerd in tip and tail. I say go 186 for size.
2013 Armada El Rey. Another good park/allmnt ski. Really well built. One Of my favorites from Armada.
Full traditional camber. For your size 178.
And for something more fat ON3P Jeronimo. A true one quiver ski. Wide but still nimble. Rockerd tip and tail. 181 for this guy at your size.
Like I said this is a short list. Just take a few days and search around to see what people got.
