Eldar Choices

Anyone who has looked over the eldar codex has noticed at least one thing: We have a surplus of units in each catagory. In the old codex, one could avoid having such strong competition for elite or heavy support slots by using a craftworld to mess around with the force organization chart. In the new codex, the "Craftworld Eldar" codex is null and void. Which poses a slight problem for me. Especially under heavy support. I have too many eldar units to effectively build one balanced list. With 3 wraithlords, 2 falcons, one fire prism, 2 dark reaper units, and 3 war walkers, I find it hard to find a perfect harmony of heavy support to compliment the rest of my force. Sure, I have options, but it might be hard to locate that "sweet spot" for multiple units to work in PERFECT tandem. Units can always work together, now I just need a list that can compliment itself but not fall apart if one or two units are lost.
