I have a kinzuadder 3G and kana v2 and i prefer the abyssus 2014 right now. Wouldn't be the case if the size of the kinzu shape would be more close to the xai (or kana at least) But that's preference. The problem is the sensors in unmodded kinzu mice. Esspecially v3. Out of my head it's an A3050. So it works probably only at 500 cpi without issues.

I heard the Kinzu v3 uses an average sensor. Aby 14 uses the same sensor as the Zowie FK / Kana v2. I use an Aby 14 and it's great.
