Well I wouldnt repeat things you already have.
What about a few leather corals. Sarcophytons can make nice center peices on soft coral tanks. Sarcophyton elegans is a great yellow leather that does well in higher current and higher light. I would get a Tracy Grey green polyp leather for AWE and grow it out.
I also like rics if you can get the right color morph with out breaking the bank. I like the nice real blue rics and the orange ones. Some one out there also have pinks that are pretty nice.
I also like purple gorgs for softie tanks, there are a few different types that do well with med light and current. They give more depth to the tank as you can
glue them to a rock in the middle of the sand.
I also like the many different branching softies and wold get a wide variety of them, cladiella, sinularia, green nepthea, lobophyton, ect...
Of course thats what I like and what I am working on doing with my system. You have to do what you like. FWIW, derasas don't come in to many different color patterns like maximas or croceas.
