Looking for a mouse similar to MX518

[Chronictank]

Hi,
I have a logitech mx518 but i am looking for a gaming grade wireless version of it
I think the mouse is fantastic but my new desk makes the wires hanging off the back of the keyboard tray an issue

I have a mx1000 too but it is not as comfortable, neither was a Razor DeathAdder (i thought it was horrible)

I dont mind about the button layout at all,
i just dont like the shape of the MX1000 and their newer range which spawned from it
The 518 is lower profile so fits in my hand far more comfortably
The razor deathadder was ok but the front buttons hurt my fingers after a while.

Thanks for all the help so far i have been trawling around for ages looking for a replacement
