I will put my vote in with the copelandii. I have one that's just awesome in my highland tank (well, with this heatwave, it's currently my intermediate tank, lol).
Jeremiah, trully inpirational rajah. I'm finally getting myself a greenhouse, which I am going to use as a highland house, so I may finally invest in a rajah, as well as some of those other, more difficult, highlanders.
