So... I've come to the conclusion that when I type in "mouse for large hands" or "carpal tunnel mouse" in Amazon, what the search function does is replace that with "mouse" or "carpal tunnel gimmick." What they don't seem to understand is that one of the most annoying Features(tm) of budding carpal tunnel is the numbness that tends to result from the motion of pinching your thumb and pinky tips together. I.e. how most people hold a gaming mouse.

I've seen a bunch of these gimmick vertical mice and supposedly ergonomic mice with kewl sculpted thumb slots, and the effective pinky-to-thumb distance is still typically less than 60mm/2.5in. Or they force you to unload your wrist onto your shoulder/elbow, which just compounds the problems of holding a mouse for precise control by making your arm tired and movement clunky.

The best mouse I've had is my Steelseries Cataclysm mouse. Fortunately I bought one for work, too, before they stopped selling them. It is close to 4.5 inches in width if you grab it by the very edges of the thing, and it's the only mouse I've had in the last decade that lets me get a solid evening of FPS gaming done without running for a bottle of NSAIDs.

I've owned a R.A.T. mouse which gets kinda close but it angles the thumbpad so much that it makes it hard to hold once you get it wide enough. I've also tried a few of the Razr mice as they're pretty big but they still are about an inch too narrow.

I'm not opposed to doing some ghetto mods to a normal mouse to make it wider, but that's not something I've done much thinking on.

Since this is the most friendly, helpful, and knowledgeable bunch in my sphere of activity, I'll put it to yous guys: where would you look for a decent gaming mouse for larger/gimpy hands?
