Best healer Eidolon?

[Onek_McPound]

Hello everyone,
I started playing this game a few days ago, and im in love with it!
I am a healer Bard sub Sorcerer (lvl 50 currently), and I would like some advice on Eidolon choice that will help me heal in later dungeons/raids.

Any suggestions?
I am currently using Aelius.
