Razer Abyssus :
1800dpi 1000hz sens 1 (23.5cm/360°)


Zowie FK :
1150dpi 575hz sens 1.2 (29cm/360°)
1150dpi 575hz sens 1.8 (19.5cm/360°)

which one to use ? any idea ?

*edit : okay i will use either sens 1.2 with the zowie fk at 1150dpi or sens 1.8, so that's basically 30cm vs 20cm, what would you recommend to me :p ?
