Logitech g502 or Zowie FK2

Solution
I switch mice every few years and every time they have new features/better DPI. It will take a bit of time to tune it to your linking but it is similar. It took me about a week to get used to the G502 from my G600 MMO mouse.

i currently have a razer deathadder,will i have hard times to get used to it??? Im afraid i will suck if i got a new mouse
