YES! I often find that I can work the better expeditions QRP after the 
initial rush has died down, even on Topband.

Where this breaks down is when expeditions QSY from lower bands at the 
first sign of daylight,  failing to understand that gray line 
propagation is usually strongest on the daylight side of the terminator! 
  On Topband, it's often great for 30-45 minutes, on 80 it's an hour, on 
40 it's two hours.
