Originally I was thinking of S-23 here, but I'm aware that Denny has not ever had success with it, and even goes as far as saying it is the worst yeast he has ever used (4 times as I recall), so now I'm thinking of S-189. I think that W-34/70 is likely to be a bit too clean for the style. Any other suggestions?
NOTE: None of the LHBS companies near me (which means within ~50 miles one way) carry Mangrove Jack yeasts.
