In addition to @Elegy I can actually only add this WOB:

Questioner

I was wondering if you know, like, exactly how tall Kaladin is?

Brandon Sanderson

Um... Kaladin? 6'-4". But you've got to remember... People on Roshar are taller than people here. So like 6'-4" compared to someone else in Roshar. But it's a low gravity, high oxygen environment which means that he's probably more like 6'-8", or something like that. Like you're gonna see... But it-- that's only-- you know, like for instance their year is different than ours too, and things like that. If you just want to imagine him at 6'-4" that's fine.

So, apparently the measurements are x1.06. Hence, when Kaladin is around 6'8", then Shallan might be 5'9" on earth. Rock - who is described as almost 7 feet tall - is probably as tall as a small Koloss!

I do agree with that, but to be a world singer you have to actually "sing" about the world, not keep quite about it. I dont think hes secretive, I think he was like all bridgemen not watching to talk about their past.

“Now, as the Truthwatchers were esoteric in nature, their order being formed entirely of those who never spoke or wrote of what they did, in this lies frustration for those who would see their exceeding secrecy from the outside; they were not naturally inclined to explanation; and in the case of Corberon's disagreements, their silence was not a sign of exceeding abundance of disdain, but rather an exceeding abundance of tact.”

—Words of Radiance, chapter 11, page 6^[

 

I agree that lightweaver is a far stretch, it was more based on his relationship with hoid than his personality. I think elsecaller would be a solid bet though.

I do think Sigzil is more secretive than most in Bridge Four. 
After all, Kaladin managed to hear the past from most bridgemen but definitely not from Sigzil - who still shuts down every time when asked about his past or a certain white haired man is mentioned. But surely, not every Truthwatcher will be" secretive" in nature. The Orders must have a much wider range of personalities with their growing number of members. 

Personally, I don't think Elsecaller would be a good fit as their second attribute is Careful and they seek Self-Mastery.
I'd rather want to see him become a better mediator. But then again, I might be a bit biased here...

Although, he could also make a good Skybreaker. He surely is focused on his paper work...

Honestly, I didn't expect such a definite result! I also assumed I'd be much more of an Edgedancer... Well, close enough.
