I am thinking about the Razor mouse - since it has bluetooth. Could anyone who has this mouse comment on the the scroll wheel operation? Is it smooth or stiff and notchy, ie specifically geared toward weapon switching in games? I tried out the Microsoft bluetooth 5000 and while is a good mouse (connectivity is great, no jitters) the scroll wheel is SO stiff and notchy that I consistently keep activating expose by mistake, usually when scrolling through a web page or document. (I usually have expose set for scroll wheel click). This is so frustrating that I its a deal breaker for me. I hope to hear that the wheel on the orochi is an easy spinner ! BT mice are becoming rare.
