Mission for multi-flyby; Eve or Duna first?

[chd]

As the subject says -- career mode, picked up a mission to fly by 6 bodies with one ship; most are moons so they should be easy, but the other two are Eve and Duna, so is it generally more efficient to hit Eve first, or Duna first? Or does it just depend on where they happen to be?

Eve gives you a better slingshot, which will help you get out to Duna, if you do the timing right.
