yeah, seriously, weights are a nice feel to the mouse, but in the end they are just epeen gamers trying to make themselves feel more pro.
when i got my mouse for my computer i HATED it cause it is a really light mouse compared to what i used to use. after about a week i got used to it, and about a month later i am pwning up all the fpses like normal. seriously, it is just whatever you get used to. if you play with a light mouse, you can own with that. if you play with a heavy one, you can own with it.
