Most international freeband activity occurs on USB on frequencies ending in '0'.
There is an internationally recognized callsign system in use on USB as well.
LSB is generally used for contacts within North America (and to Europe when conditions are good), and mostly on freqs ending in '5'.
I don't hear many if any needle benders on USB.
