WotLK Shadow Priest Pre-ICC trinkets

[moshima]

Hi, I have a Shadow priest with 4T10 items (264 ilvl).
I'm looking for trinkets that could be purchased with Points.
there are multiple options and wondering which two are best?

http://wotlk.cavernoftime.com/item=47726 (flat Haste rating stack which is bring me near soft haste cap during fights)
http://wotlk.cavernoftime.com/item=40373 (just bcz of DoTing nature of SP, according to wowhead 15% proc chance and 15sec CD)
http://wotlk.cavernoftime.com/item=45866 (I'm cap on hit makes its passive useless)
http://wotlk.cavernoftime.com/item=47213
http://wotlk.cavernoftime.com/item=47182 (cannot purchased with points but worth to mention)

I would suggest go with the first 2..
As you said.. flat haste burst and crit / SP buff on " flare ".. these sound good till you get into raids and get cts +Phy / Dislodged ( some people get this instead of phy for haste ).

Abyssal Rune and Talisman of Volatile Power

From all the 6 mentioned you must take only abyssal rune.
The first and the last one lets say it could be many many many months until you see one of them dropping and its high chance you won't get it.
The second one which you must have is nevermelting ice crystal.
These two you can use well into normal 25 icc.

I don't know if you've read this guide:

but if you did, you didn't understand it properly otherwise you wouldn't have considered №2. 3 and 4.
There's much, much more to the spriest than this guide but it still gives plenty to have a good foundation.
