currently using G5 with weight change function actually i dont feel it useful because i not using it add weight or not makes me feel just a bit different 

There are a few gaming mouse with weight options. Logitech has the G5 and G9. The new Microsoft Sidewinder mouse has this option too.
The Razer Copperhead can be tuned with weights. But it is an extra as it doesn't come with the package.
I'm using the G9. The weight is very subjective. Some say its useless while some swear by it. All depends on user. Of course a heavy mouse will tire you faster.
The reason for the weight tuning is not for everyone. All I can say is that it does make a difference for those who want to tune the mouse to how they want it to move.

whats the difference between 3g laser with normal sensor??
thx in advance

this FaezFarhan i wonder if related to hellkeeper or not.
this guy go on and on about how hes a fingertip grip user, and now want to get x5?
i lost track of what mouses he wanted already...copperhead...diamondback...ikari...x3...x5? whats next? g5? g9? a4tech?
somemore x5 suits his style of a fingertip user? 

seriously, just forget ur orientation or whatever at uni and go for PC FAIR and try them all.
