Best Mouse for FPS?

[EarnSomeRespect]

I'm really trying to decide on what mouse to buy here. I'm really leaning toward the G502 but I want your guy's feedback. I need an amazing sensor and no hardware acceleration. Should I get the FinalMouse, Fk1, G502, Deathadder or some other mouse and why? Thanks!

My 2 cents on this topic is always: Mind your hands. I have huge hands and my choice of mice is always between the widest mice to avoid cramping while playing.
If you have very big/small/strange hands take this into consideration. Go to the store and try them.
