Thousand Sons, paint schemes and crisis of faith.

So I have had a crisis of faith with regards to my chosen paint scheme for my Thousand Sons.

I know, it is probably not the time to use that saying, especially as it is only in relation to my nerdy hobby, but it still expresses how I feel.

I used to dislike the more traditional variations of blue/gold of the Thousand Sons.  This is what pushed me down the path using the pre-heresy colour scheme.  However as I wanted to see what the Dark Angels robed bodies were like I thought I would paint one up more traditionally.  I tested out some blue, and some gold.  Then at Paul's behest weathered up the robe and used a mega dry brush on the edges of the armour (mimicking edge highlighting).  It needs a weapon, and a bit of tidying up, but the result is below.

Traditional colour scheme with robes.

And this is where I came to my crisis.  I was surprised how much I liked the traditional look, more so than the red I have been painting.  After much soul searching, deep thinking, and random dice rolling, I have finally decided to go with it, and eventually strip and repaint the old red guard.

My final products will be a slightly different blue, as I am going to use the Army Painter Ultramarine spray over a dual primed model.

A few questions now remain.  Should I do the lines on the headdress yellow or gold?  It varies on units and images you see.  And what should my dry-brushed highlight colour be?  I feel the green is probably a bit too alien next to the Ultramarine.
