Druid/Shaman or Shaman x2?

I decided I'll get my RAF done on my horde server, and I thought that after not enjoying Priest/Mage very much I'd like to do something a little more straight forward. Do you guys think I should stick with dual shamans, or go with druid/shaman. The benefit of the later is that I can have a leveled druid on this server, as druid is my current alliance main class, and I think that the main druid tank in my raid guild kinda sucks. With shamans I'd have two, and I could have elemental and enhancement.
So far (14 levels) druid shaman isn't difficult to manage, other than needing to place some keys better so I can earth shock or moonfire independently.
