Completely agree with Philpug (no surprises there). I spent a fair amount of time on the Volkl 90eight in 170cm, which I thought would be okay because I'm quite light for my height (145lbs, 5'10). I found it bounced me around a bit, but I never felt out of control because of it, even at speed. It turned very quickly, and felt so light on my feet it was unbelievable. I suspect I would have been bounced around less on the 177, but I didn't get to try it in that size. The Enforcer 177cm, which I went on to buy, felt quite different. Slightly less manouevarable (partly because of the difference in the lengths of the two skis I tried, I'm sure), but very smooth and quiet and ultimately more reassuring. Great in most conditions, although very hard icy snow is not its strongest suit. I preferred the Enforcer, even at my weight, but both were excellent skis.
