I've done a little research of my own, but can't come to a conclusion. I've managed to at least find them all, so I'll list them here for people to comment on. Steelpad series --------------- SteelPad 4D? Steelpad 3S? Steelpad S&S? Steelpad 4s? Arrrr!!! Icemat series ------------- Black Icemat Black Icemat 2 I've heard the heavyweights are the 'Black Icemat 2' vs 'Steelpad S&S', but recently I ran into another review that said the 'Steelpad 4S' is better than the Steelpad S&S, so now I'm really confused.
