Hard pads are always great. But, you might have wanted to give the RedOctane pads a look. You can usually find some selling fairly cheap on ebay. They're soft pads, but they're the best soft pads ever made. They hardly slip, and you get a real good feel for them. But hey, you have a metal pad already, so meh.
On a sidenote, if you enjoy DDR, I recommend you check out this site:
