Hey, I was asking myself that question and here is what i came with (for solo content). Some advice/comment/testing return from our fellow lvl 50 SMN out there would be greatly appreciated

Solution 1 : TANK
+ Let your chocobo tank and dps with garuda + your dots.
- You will have to heal the choco.

Solution n°2 : DPS
+ Tank with topaze Carby/Titan-egi, and let your chocobo DD.
- You will have to heal the chocobo

Solution n°1 & 2 are kinda the same, just sweetching roles tank/dd. The question here is wich Tank/Dps combinaison is better (who tank best might be more important than dps for solo content) ? Will our chocobo be able to tank better than Topaze Carby/Titan-egi ??? Need some test here...
