What's with the sniping over the choice of US WoW or TW WoW? It boils down to personal preference at the end of the day.

Anyhow, if you're playing on US Servers, best invest on a proxy/tunnel as well. It will significantly improve your latency if you're on a bad line like me. (I get upwards of 600ms w/o proxy, but stable 300ms with proxy).
