Would love to hear how that Black Widow works out. A lot of reviews at newegg sound negative but if my g110 dies at some point, the black widow would be one of my first choices.
One note about their software. Once installed, have a look at Task Manager. I noticed my razer software seemed to be using 25% of my CPU at all times, even at idle. I killed the tray icon, and recovered those cpu cycles. Mouse still works and shifts just fine as the driver isn't affected and they unload their programming onto the mouse itself (I think).
Anyway, enjoy the new toys!
ps. question on the Black Widow if you have time at some point. Is the headphone and mic jack just a pass through? The g110 apparently includes a mini-soundcard instead of a straight pass-through for some completely inexplicable reason. Means I can't use them as there's no way to get enough volume out of it. Had I known that ahead of time I wouldn't have bought it.
