I do 2 packs of T-58 for the triples and quads. Always gets the FG to where it needs to be (10%+ ABVs). It is fast, starts fast, ferments vigorously and is probably done in four days though I leave them all for three weeks. The krausen has been moderate and falls like normal as far as I've noticed. I use a 7.9 gallon fermenter for a 5 gallon batch so I can't gauge its performance as it relates to blowing beer out the fermenter--none ever have.
For fun, not because it was needed, I just pitched 3 T-58s at 66°F and 56°F room temp (I don't do electronic temp control). I got a little bit larger krausen but it still took the same amount of time to finish. I'm looking to see what kind of flavors this change produces. Even if I goofed by pitching three, it's all good. Smell was a little milder from the airlock.
Another yeast, M-41, in combination with T-58 took my expected FG .004 points lower two times in a row. Two M-41 on their own, took my beer .015 points below expected.
Who's the monster now? (I'm just kidding around)
The thing with M-41 so far is that, though it ferments the bejeezus out of the beer, it's been pretty cloudy in the bottle, whereas I usually see it clear up better by this time with just T-58.
