Though I will probably use 1, I must point out that 2 is perfectly acceptable. Ken Smith, a reknowned luthier (specializes in top-shelf basses), will ONLY use 2. After a steam pipe broke one afternoon, he found (after the weekend) that all of the joints using 1 were ruined beyond repair, and the ones with 2 were perfectly fine.
As for 3, well, I might just use 3 as an experiment - I have a bottle of that, too.
