Mattyfng, you and I are pretty similar in size (I'm 6', 165), and ski many of the same places. Every ski suggested here is excellent, but they're all over the map in terms of feel, match to skier, and mission. So of skis I've owned, demoed, or had good skiers I know evaluate, my recs. Your milage may vary:
1) At your weight, avoid beefier skis (think Nordica Jet Fuel, Volkl AC30/40, any upper level Atomic, many Heads, most Stocklis, Elans, Blizzards) unless you like to ski fast, and can carve well consistently to flex them. Even then buy them short. In which case, my picks in order of preference for you would be the Stockli Rotor in 169, last year's Titan 8 in 168, a Volkl AC40 in 170, or a Head Supershape in 165. Lot of folks I respect like Nordicas and Atomics, I just can't love either. But recs there probably would be Nitrous or the B5/11 respectively.
2) Avoid skis predisposed toward softer snow (think most twin tips, Dynastar Legends, Scotts, Rossi Bandits) unless you're going to emphaszie woods, soft bumps, or what backside pow you can find in NE. In which case my order of preference would be the Fischer Watea 84, Line Prophet 90, PE, Stockli Coral Snake (buy short), Legend 8000.
3) Skis I've found to do well in everything back here include (again in order of pref) almost all Fischers (especially recommend the RX8/Fire if you're more into straight carving, Cool Heat for more all-mountain); as barrettscv says, the Dynastar Contact 11 is a great all-rounder cross design, likes speed but also rocks in bumps and tight spaces, tail can be scarved/smeared like a twin tip; the Rossi Z9 is light and smooth like the 11, but better at tight radius turns, bumps, lower speeds, not as good in crud/pow, higher speeds.
If no demoing, suggest more homework. IMO, reliable sites for reviews that emphasize your needs include searches here (pay attention to size, skiing style of reviewer), Skipressworld (excellent numerical scales), Ski Canada (which matches fav skis to particular testers.) Semi-reliable sites (meaning very useful given some built-in biases) include Skiing, Ski, and three shops: Foot Loose Sports, Sierra Snowboard and Ski, and Ski Reviews UK.
