i do know pal and to be honest I've tried them both how? well the kinzu v2 pro was sent to me because i bought it from an asian friend in taiwan and let me tell you that the sensor of the kinzu v2 is just FLAWLESS, its awesome and the best of all small-hand gaming mice around...
It has a heavy prediction (even heavier than the MX518) . There's also hardware acceleration. I don't know what you mean by "very good". It's very bad in my opinion compared to leading gaming mice in the market today.
so say me why do u need this stupid lights, high dpi and not necessary features? it doesn't cost itself. wireless? haha) ofc you will play in wireless mode at lans) :D
this "improvements" from razer are n0thing. imho
as far as i know, kinzu v2 hasn't been officially tested yet. between those two i would choose deathadder, althoguh imo xai is the best mouse ever.
choosing between those two is personal preference (as i have stated in #8)
i have kinzu v2 pro and i tryed da so its realy simple kinzu works on qck heavy and i hope other pads :)) but not un qck + , navi fnatic tyloo eg or eny other in this class and is very good for small hand da is perfect for big hand so the only criteria is haw big is your hand :D (in my oppinion)
I am happy owner of zowie am, and it beats Deathadder in my opinion, sensor have very similar performance. AM's shape is better, LOD is better. The only advantage DA has over AM is scroll which is superior in DA.
