Myth Question

http://na.finalfantasyxiv.com/lodest...racter/139731/

Here is my whm, having trouble deciding what to upgrade next with Myth. I farm t1-t4 weekly (haven't done T5 yet) so it's fair to say I have access to all those pieces. Whether i'll get them or not in a realistic time span is another question.

I have decided to go the determination build which means that a lot of my CT is far from desirable. I also have a penta-melded astral choker with 8 vit in it which is my lowest ilv gear.

Should I go for cleric pants next? Or the heroes neck? I am having no luck getting the allagan neck from t2 because of the stupid enrage method with 3 healers, someone always needs it and the two weeks it dropped I lost need rolls. I am hesitant on the body because it seems like allagan is BIS for what i'm doing here.

Am i right to think my best myth upgrades here are:

Pants
Feet
hands
belt

in that order? Any help appreciated!
