It sounds to me as if, of all the methods you mentioned, you would prefer

How would you vote with SODA?

(go ahead and think of your answer before you read mine)

I think I'd almost always just delegate to my favorite with SODA. If I
don't like my favorite's delegation order, that would make me reconsider
whether they're really my favorite. If I decide they still are, I would
consider whether I thought the difference between my preferred order and
their predeclared preferences would matter. If I decide it does, then look
for the best candidate I think has a chance, and vote for them and everyone
better. Chances of me ever getting to that last step would around one in
10, I reckon.
