I don't even notice the added weight in my pocket, but when I hold it, it's heavy enough to know that I have something in my hand. It's actually pleasant in a way that cannot be described.

Even though I loved the aluminum TS10's enough to get four of them before copper was an option, I've barely touched the my aluminum ones since getting one in copper. It's that nice. I won't say that it's better than sex, but it's good enough that I'd have to think about it for a moment if asked to compare the two.
