I did a set of test batches of my Michelob Dark Clone with 4 different yeasts a while back. The Edinburgh was the slowest to start. But when it did, WOW. All jugs were of equal volume with plenty of head space and it was the only one to come out the airlock.
(BTW, the others were US-05, American Ale Blend and Thames Valley.)
All four brew were great, but the Edinburgh got an A+ rating from me. It gave the brew a slight but distinct rich flavor note compared to the others. Definitely a keeper.
