For a long time I used and preferred wireless mice. But then I went and got an optical wired one designed to be light (70 grams) and its made a world of difference. I move the mouse a lot faster and the flawless nature of the sensor makes me more accurate. 6 months with this mouse has improved my game dramatically and I feel like I am the same player that one championships 10 years ago. I don't have the mind skill but the physical skill has returned. The problem I had all along was a string of terrible mice supposedly gamer mice.
Its not that wireless sucks, but we should really talk specific mice because there are very very few that are actually any good, wired or wireless for gamers.
I no longer frequent these forums.
