I think its about time to get a new mouse. my trusty old G5 still works like a champ but ive had it for a long time. I was thinking of getting the G500, fast said it was similar in feel to the G5 just upgraded a bit. Or i was thinking the Razer Mamba. Anyone have any other suggestions? I like to have some decent dpi 4000+ and also some extra buttons for my thumb to use. Adjustable weight is a big plus. i like a heavy mouse i have 27.6grams extra weight in my G5.
