Do you have to decide for yourself? If your aim is good, and you can build well, edit it fits. If you do not hit the opponents that well you can try a little less.
Somehow everyone plays a low-sensi. I play 1800 DPI and 0.219 ingame others maybe play 800 DPI and 0.050 in-game…
Everyone is different. If you get along so well that fits ^^
I play 1800 dpi and 0.151 ingame
