Help: BIG quiver rounding ski

Hey guys. I have a chance to get any 06/07 K2, Dynastar, Atomic, Blizzard, Head, Nordica, Armada, Liberty, or Volkl ski for cheap. I'm 5'9", 130lbs and an agressive expert skier. I currently own AR5s in a 170(park/urban), Titan 9.2s in a 181(resort everyday), and 178 EXP Pros(shitty touring skis). Now I'm in need of a big ski for charging big mtn lines, pow, and basically just going big in places like Squaw, Utah, and Krasnya. I'm currently trying to get together a film and competing in several big mountain comps next year. So far what have sparked a little interest have been the:

Dynastar Legend Pros 176, 186( 186 may be too much ski, but 176 may not be enough???a little help?)
Atomic Thug 181cm(HUGE..maybe to huge?but my favorite right now)
Volkl Gotamas 183cm(Increased side cut may suck)
K2 Seth Vicious 179cm(May not be enough)
K2 Maden 179,189cm(May be to soft.Not stable enough)
Volkl Sumo 175cm(May be too much sidecut, or not stable enough)
Head Mojo 105( Similar to Gotama in shape, but softer?Can anyone confirm?)

I know its quite a bit, but I have not got a chance to demo any 06/07 skis this year.If any questions could be answered that would be helpful. Thanks guys. I'll make sure to post a review and pics of the new skis!
