The mouse I use for day to day operation is the Razer Viper 1000DPI optical mouse, this is probably one of the most accurate mice on the market and is primarily designed for gamers and graphic design wizards. The mouse performed perfectly on the Corepad actually surpassing my expectations, the Icemat we reviewed some time back had trouble with super fast movements but the Corepad held true through many games of Vice City and UT2004.
