On the other hand, volkl falls at the softer spongier end of the spectrum. You may give up some advantage in edgehold in exchange for quickness though.
At your size I would think that the Volkl would be faster... but if you are used to a stiff GS ski and are finishing well on it and are comfortable on it - go for the nodica.
I have last year's Racetiger in 165 and I have to say, the edge grip is definitely not lacking. I have not tried the Nordica but I could not imagine a grippier ski than the Volkl. It's also on the softer side, which may be more suited to your weight. Being shot off-balance out of your turn when you're trying to get ready for the next one isn't really an advantage with the current technique. The Volkl has a really nice damp, glued feel to it and really allows you to push the limits.
I have heard great things about the Nordicas but have also heard that they are extremely demanding.
I have also tried skis from Rossignol and Head, but not of the recent batch. In my experience, the Head slaloms I was on feel a lot like their GS, very damp and stable, but not super-quick. The Rossis I have tried, the latest being that of two seasons ago, felt very light and quick, but didn't have the same solid grip as others. But I have heard better things about the newer ones. However, I did get a chance to spend a day on 2 years ago's world cup stock, only available to sponsored athletes, and that one felt amazing, a lot like my Volkls but a bit less energetic. What I noticed most about them was the feeling that the entire edge of the ski was gripping, rather than the area just underfoot. My Volkls feel like that, too.
