I'm an XTrac man...after attending the owner's LAN parties and beta testing the original XTrac pads I fell in love with them and will likely not use another mouse pad until I am forced to. I have used the regular old XTrac, the Hard Surface, Ripper, Pro, Zoom, and Hybrid...I have to say my favorite is teh Pro because it is cheap and good, and hell I don't need a mouse pad the size of my room. I would not recommend the HS pads as they do not last very long, usually 6 months, while the Pro I am using has been under my wrist for nearly 3 years without a problem at all.
