5U6E seems to spend all his time on CW, and I have heard him spending a lot of time listening for VK/ZL and W6/7. Often the Europeans keep calling, frustrating him and at times driving him to go QRT.
5U5U does seem to be focusing on RTTY, and my experience mirrors the other poster, was easier to work than 5U6E who had a significantly larger pileup.
Best of luck!
That is good to hear, there is hope yet !
