I am 6'4" and 250 lbs, so I am in the "big guy" class. I have been shopping for new skis this past season and bought two pair, SkiLogik Ullr's Chariot, 101mm underfoot, 178 cm long and Rossi Radical 9SL TI slalom race skis, 70 mm underfoot, 175 cm long. The chariots are fine at this length, but they make a 188 cm that was my first choice and I would recommend that for you. I bought used and didn't have a choice.
In general, we want a ski that is 180+ long, 185 cm is a good choice, unless it is really stiff (such as the rossi's) and then you can get by with a 175-180 cm ski. One of the best all around skis for us is the Dynastar Contact 4X4 in 178 cm, which is not made anymore.
The bones would be a good choice, get the 187 cm length. Depends on what you want for a ski. The Chariots make a great one ski quiver for a wide ski (90-100 mm), the Bones will be in the same class as the Chariots. Check out SkiLogik, they will ship all over the world and the prices for new skis are reasonable. You can also go with a 80+ mm wide ski as a 1 ski quiver, such as Kastle MX88, Elan Amphio 82 Ti, and others as long as you buy the 180+ cm length. Check out the "for sale" section, as someone is selling a MX88 in 180+ length that would work well for you.
I decided to go wide, and then go SL race ski (rossi's) for my second pair. They are so stiff that they will perform well on hard snow, not too good on soft snow, but I haven't skied them yet, so I don't know for sure.
Skis I would recommend are: Dynastar Speed Course Ti, Elan Amphibio 82 xti, SkiLogik Ullr's Chariot TT, Blizzard Bonifide or Cochise. There are lots more, PM me if you want and I can send you my "short list" of skis I looked at and tried. You need to explain what you are looking for in more detail if you want better/more advice.
