PVP healing trinketFollow

I am trying out more arena on my paladin and I was wondering what would be the best pvp healing trinket.

I already have http://wow.allakhazam.com/db/item.html?witem=28236;source=live

I need to fill up my second spot, in my inventory, I currently have http://wow.allakhazam.com/db/item.html?witem=28190;source=live and http://wow.allakhazam.com/db/item.html?witem=28590;source=live

Also, I could probably get my hands on any other t4 trinket out there. Feel free to post other tinket suggestions.

Whenever I PvP as holy, I use Vial of the Sunwell out of Heroic Magister's Terrace. It's macro'd with holy shock and divine favor, and the macro looks like this:

/cast Divine Favor
/use Vial of the Sunwell
/cast Holy Shock(Rank 5)

If you have the arena 4 piece set bonus which gives and % increase to the amount that Holy Shock heals for, you can basically have an insta-Holy Light once or twice an arena match. The trinket can crit heal for 3k and I run arena with ~1800+healing and my holy shocks crit for about 3.2kish. So you get a 5-6k instant heal, which is awesome when you're running for your life or when you're trying to avoid counterspell, etc etc.

The only usage I can see for the ribbon is when there's more than one person healing a single target or the same multiple targets. A good example is when someone's tanking Vandar or Drek (in AV) and a couple of the warmasters - they need more than one healer to keep them alive.

For arenas, well it has a nice equip bonus but that's it.
