I'm in 6-land and work EU all the time on SSB and CW. Timing is everything. I do have a 20 meter beam on a 55' tower, which helps. A lot of the stuff is weak enough that if I switch to my vertical it's simply "gone." The actual difference between the beam and my elevated vertical with a lot of radials is only about 10 dB, but that's a very big 10 dB with the kind of condx we've been having.
