I'm a microsoft intellimouse 3.0 lover. For me its the best mouse ever but it have a mousebug that makes me rage. I know some people who already fixed the bug but no one tells. ( no papper fix )

I'm playing recently in a good level CS:GO and i need a mouse who have a flawless sensor and a good shape.

The question is: should i go to another 3.0, the new Deathadder 2013 or G400 ( not very sure if im gonna like the shape)

I need a sensor without flaws, negative or positive accel because i use a low sensivity !
