I used this yeast after stepping it up two times then split the yeast into two carboys, both having the same wort, same quantities. The yeast was very fresh and at first I wasn't sure what I was seeing after only an hour and a half or two in both fermenters, foam from aerating or yeast at work because I still had a nice layer at the top. I did see slight activity in one airlock, nothing vigorous only a slight rise in the one. Sometime in the night both took off nicely though and I could see with no doubt the yeast was working because it was definitely krauzen and both airlocks were plunking away. I had pitched the yeast at about 60 degrees.
The funny part is this, today only one was working (judging by airlock activity anyway). I've since moved that one near a heat supply vent and its working again. The other one which is the carboy that actually received the least amount of yeast, because I couldn't judge accurately the amount I poured in the first carboy, has never stopped showing airlock activity. Here is what I think happened. Although I left some liquid after decanting and swirled, a greater quantity settled to the bottom possibly so the second carboy may have received more yeast cells than the first carboy? It really doesn't matter I suppose but it has me curious.
So far I like this yeast. I love the smell, its definitely got a soft yeasty aroma which I hope will be there in the taste as well.
Another thing I can see that I will like is this yeast does seem to like it just a little bit warmer, I've got it in the computer room which is roughly 64 to 65 degrees so it might be a good yeast during the warmer months. Just tuck your fermenter away in a somewhat cool spot during summer and I bet this yeast willl perform well and hopefully not create fusels like other yeast might.
Just thought I'd post my opinion on it so far.
