Seeking advice on Myth choices

[Aurelious]

Hello everyone. I wished to ask the community on what should be my first choice for my Mythology. I will have 826 Myth after I finish capping tonight, and been wondering what I should spend them on. I am a Paladin and will continue to be one for a long time. I have currently defeated Garuda HM and have not yet attempted Titan HM due to wanting to be properly geared for the fight. Below is my current gear:
Ifrit Blade \ Darklight Shield
Hoplite Helmet, Chest and Feet
Darklight Hands/Belt
AF Pants (haven't found an upgrade yet)
Darklight Choker, Earring, Ring and Wrist of Fending
Amber Ring HQ

Sitting at 403VIT (30 Attrib in VIT), 4954HP before food/party buff.

As it stands doing Garuda HM trying to go for my weapon just to give a bit of an edge over the Ifrit weapon. Here is where my question comes in.

I want the Valor Surcoat as 1) it is shown in multiple threads to be BiS and is something I will strive to get anyway and 2) It helps me skip the darklight armor chest piece which, while minor, is something I would be grateful to do. Plus by choosing the Surcoat it enhances my VIT and tanking ability which helps me get into Titan parties so I can get my relic.

However, the usual pick for first myth choice is the +1 Relic. In the case of the Paladin this would be the Shield to +1, which getting the surcoat this week I can do the relic +1 next week with capping, which I plan to.

So does this sound like a good plan, or is there something I am not considering? I appreciate all advise and look to be capped by tomorrow evening but will wait a bit before making my decision. Thank you again.
