Does anyone here use cutting mats with optical mice, and how well do they work? I'm talking about the green "self-healing" mats. Most important, do they give too much resistance to moving the mouse around (they always worked fine with traditional ball mice, but optical mice I'm not so sure about). I hear that green is a good colour for red LED-based mice to track (I had some issues with a Microsoft mouse, and they listed a load of colours that they don't recommend for optimal tracking including, blue), so that shouldn't be an issue.
For the past few months I've just been using the mouse directly on the desk, but I can see that it's starting to wear the surface shiny, and wonder how long it will be before I wear the colour off as well.
