I have never ridden the DaNollies but I bought the Vishnu Wet in 183 this season and I am thoroughly impressed. They are symmetrical, and they butter and press really well, but they also have a good amount of pop. I have a really fun time doing ollies, actually loading up the tails and having them spring me up. Nollies are a bit wierder. due to the curve of the tip, if you lean very far forward they will auger into the snow, but I think it's just a matter of time. They are the most fun ski I have ever owned. They are a bit narrower at 87mm underfoot, but I haven't had an issue with that, even when riding 14 inches of powder at Stevens Pass this season. They were pretty much always under the snow, but due to the tip and tail rocker, and the fact that they are incredibly light, and thin at the tip and tail, I pretty much didn't lose any maneouverability.
