Correct Healing spec.. with PI and without %Spirit=Healing

So after getting yelled at in a dank premade for not having power infusion like a bad kid I decided to look at talents again with consideration for AQ40 and even content that's already out and FOR SURE 100% PI is something that outweighs your 50 +healing or whatever you get, I don't know the actual number, but I assume its between 50 and 75 +healing, which, when you have your best in slot gear with 800 +healing or whatever, it really isn't a big deal losing that especially when one of your big dong casters gets a huge damage boost in exchange.
So, with aq40 in mind, I made a few specs, not sure which one is the most worth it, I assume the difference is very small in the grand scheme of things, but discussion is encouraged.

The difference is either you take 1/2 Martyrdom and 2/5 Force of Will or 2/2 Martyrdom and 1/5 Force of Will in the Disc tree and either 4/5 Holy Spec no Holy Nova or 3/5 Holy Spec with Holy Nova, pretty freakin similar and kind of a no brainer I think?
A lot of priest talents are up to personal preference and what the individual values. Personally I think going 2/2 Martyrdom and 2/2 Imp Mana Burn is better than 2/5 Force of Will. I can also see the viability of going 3/5 Force of Will instead of Martyrdom and switching to damage gear for mana burning with a PI on yourself, but personally I think even in that situation, if you're having everyone that can mana burn actually doing it it's more worth it to PI someone else since with basic coordination it's not hard on this server to mana burn and not wipe the raid.
I mean I wrote all this up and thought about these for like 20 minutes tops so I might be missing something big so just feel free to yell at me if you see something really stupid, but I think these options are solid, and no, putting more points into threat reduction is not worth it.
