I used this yeast last Saturday. Lag was short and there was plenty of airlock activity within a few hours, which was vigorous for about two days, then slowed down and is non-existent now, 6 days later. The temperature was steady at around 63-64. I haven't taken a gravity reading yet, so I don't know if it's done or not, but I plan to leave it another week before doing anything else to it. I do 3 gallon batches and there's just enough headroom in the bucket, I didn't need a blowoff but had one on standby just in case.
