Pala Holy or Retry for PVP

I want to make a pala with a spec for pvp but I don't know which one to choose and I wanted to ask you which one to choose.

Both are very strong in PvP.
The decision is up to you.

Do you want to hurt your enemies or heal your allies?

You can also play protection or hybrid ret/prot if you want, both are viable.

Edit: all 4 are viable and good, so it depends on what playstyle you like.
