Ken: Yes!
Graphitone: I'm not left handed but yeah it's completely symmetrical. I'm very happy with it. It is very much a gaming mouse: not a bullshit gaming mouse with loads of buttons, weights, LCD screens, bits that glow and removable bits, made for idiots, but a proper gaming mouse. Which means a very good sensor, very good buttons and no hardware interpolation at all (no smoothing, acceleration or angle snapping at a hardware level) and high polling rate. It's also
extremely light. So it feels
very exact, even twitchy compared to other mice.
If you want something like that then it's currently the best, along with recent Razer Deathadders.
I'd avoid Steelseries. They're marketed as gaming mice but the hardware isn't really that good and they also have smoothing/acceleration.
If gaming isn't your main priority and/or you want a more desktoppy mouse then I'd go with the Logitech g400 which is very good (not ambidextrous though, I dunno if they do a left-handed model).
Edit: Also while the FK1 is designed for a claw grip it's comfortable when palmed too (I claw when playing games/working and tend to palm when doing idle desktop stuff. I have big hands too).
