When the aura masteries are underway if you've SSed early enough it will be off CD, so you may be able to get off another set to tide over until the stack. Aura masteries might not give you full SS coverage for the second, so remember you have access to Inner Focus to get off the last 1 or 2 PoHs during SS. I have also experimented using my second SS on more shield spam with the 4 set, which seemed to produce similar results - remember though that shield spam is hard on your mana.
I really to impress what s/he said about the mana CDs immediately - if you do a short P2 it's not quite as bad in some ways, but from the 2nd screech phase with the shield spamming and mass dispels it's going to be absolutely BRUTAL on your mana - it's imperative that you have enough mana for the 3rd screech phase. I have found myself so low that I was unable to use my barrier on 3rd screech phase and it was Not.Good.
Disc is the healer (With the possible exception of resto druid) who is going to have the most mana problems on this fight, mainly due to the spamming of expensive spells, and the responsibility to be doing mass dispels, so make sure you call out or organise the mana CDs available in your raid; remember there are:
Hymns of Hope from Shadow, Disc or Holy priests on a 6m CD.
Mana tides from resto shamans on a 3 minute CD.
Innervates from druids (Though a fat lot of good they are).
Mana tides should be used at the end of each screech phase or wherever they come off CD and depending on the number of priests, it might be worth staggering them i.e. 2 after first and another after the 2nd or something. Running out of mana during a screech phase is not fun, so try to keep a moderate amount of regen going on.
