Also, when you are sweeping, you are basically melting the pebbles so the rock doesn't curl, right? So by the end of a game, how come the ice still has curl to it? I figured all the sweeping would have worn the pebbles down so much that the curl would be gone. Can anyone shed some light for me?

I think I answered this the other time you posted the question, but I'll post it again: when you sweep, you're just taking the tiniest amount off the pebbles, but what you are doing is creating a thin layer of water between the ice and the stone, which reduces friction, and makes the rock run faster and curl less. This water freezes again in just a few seconds. It generally takes many ends before the pebbles really start to wear down.
