I am in the same boat, but I did some looking around. You will probably want the Oumo as it sounds like it's a Manchurian type. The Paladin knot I assume is the same as pictured on their site. I wouldn't even have had this confusion without the Oumo option and I assume it's being offered for a good reason(2018 batch).I’m still waiting for the knot descriptions.,
I might end up missing out or saving some money I’ll end up spending on a WR4. <eg>
