I currently have a Razer Salmosa Asian Edition which I love, I've always prefered using a small mouse. The spec is 96 x 54 x 33mm and 45g

The left mouse button is starting to get a bit shitty and will double click or sometimes not register, for instance when using LG holding down the mouse it will switch on/off firing.

Are there any decent mouse out there with a similar size/weight?
