There have been some good suggestions and I would add to look at Ski Logik's line. I bought the Ullr's Chariots this year in 178 cm. I am 6'4" and about 250. I ski on the East Coast and wanted a short radius turn ski. I absolutely love the Chariots and they don't feel short to me at all. I bought the length because I bought the skis used and was the only choice at the time, and I have to admit I was concerned. Once I skied them, no more concerns. These are rugged, fairly stiff skis that ski longer than their length. Don't have much powder so this length was a good choice. For Western skiing, I would think the 188's are the way to go.
I have not skied their other models, but they have similar construction and should have a model that fits the bill for you. I read RobertRS's post and think he nailed it.
