I have 7 stardusts (3 of the v2 non-rebuildable, 4 of the v3s) as well as a mini nova. I much prefer the nova in terms of size and sleekness, however I feel like I get a much better flavour out of the stardusts, though that might be a head issue. Either way, I'm done with stardusts due to leaking and massive juice hits so vivi's for me until I find a carto that I enjoy.
