Mark, all I used was a Microsoft 2-button mouse on a very mundane, regular small mousepad. My sensitivity settings are usually in the neighborhood of 25-30%. Seems to work fine for me. The higher, more frantic stages of the game will require greater movement accuracy than a keyboard can give you. An example of this is my Millipede recording where there seemed to be countless close encounters and subtle manuevering...something that I don't think could have ever been done with a keyboard. Hope you guys can resolve this in time for T2 (the second MARP tourney!) in case it becomes one of the picks. ;)(posted 9575 days ago)JoustGod...errr...John Rhodes
