Hey brother, if you're serious to play CS than I would suggest to go with DA 2013 if you prefer palm grip otherwise kinzu v2 for claw grip.
Reason why not DA old model and kinzu v1: DA old have some bugs, bad quality than steelseries but still good sensor though you won't find those problem in DA 2013 which is really good and all previous model bugs are fixed so buy newer edition or if not available than at-least go with DA black edition.
Kinzu have some acceleration problems (this is what other pros. told me after using) and should not be preferred in any manner rather than go with kinzu v2 which is excellent mouse and the only problem is with sensor.
* Both mouse are superb for FPS games (CS) and in the end all what left is your choice finally acc. to your grip and I would like to mention that both mouse performs better in cloth surface.
