I currently have a 21 BD / 33 SIN / 12 INF

This is my main role and i love it! however, i would like to have some different play styles but i'm not sure where to begin.

I would love to try Sab and Bard, i have room for additional Roles so i won't need to replace my main role.

Could someone tell me, which 3 souls are recommended via the community (not in-game) for sab?

also, i would like to be a support/healer in WF's sometimes, what 3 souls go well with bard being the main one.
