Kana has a very high LOD (Lift-off distance). So I wasn't really happy playing it.
I would recommend Zowie products. AM/EC1/EC2 depends on the preference of the shape. EC1 is very similar to Razer Deathadder. Kana is almost Microsoft Intellimouse 1.1a but a little bit smaller.
And EC2 is less curved than EC1 and slightly shorter.
