well reporting back now... the HD's after break in, are actually a lot more smooth and slicker now than the perfectglides.
I am using them on the a 9hd mouse pad.. Also the xai feet have a lot more surface area than my old MX518.... soo its really hard to make a good compairson sice they are completely different mice... Either way i reccomend the Hd's over the perfect glides hands down,,, the extra couple bucks are sooo worth it, just because of the durability and to think I orderd a set of 3 of these things, the mouse feet will outlast me I bet.
