Democrats Abroad Primary-Like-Thing

I get to (sort of) vote in Super Tuesday after all! Who knew that there was a Democrats Abroad primary? Not me. Apparently, there is one, for the week of March 1–8. Apparently I’m just on my own hono(u)r not to vote twice, but they actually get a handful of convention delegates, so I’m thinking about it.
(some information).

Strategically, is it better for me to do this, or to wait and vote as a Californian? I’m going to the one in Vancouver on Friday here either way, just to see what it’s like. Apparently I can bring my passport and local ID and register on site if I’m inclined to vote.
