i've used it quite a few times for my brown ale with good results. i try to keep the temps down in the low 60's to keep the fruitiness to a minimum though. s04 ferments and clears very fast... i think the big flavors of an american brown are fine with it, and i personally like american hops with the fruitiness of the yeast.
Haha, hilarious. I don't often use the 11056/US-05/001, but it has its place. It sure doesn't bring much flavor to the party.
S-04 will make a great brown ale. If it's a real American style taste you're after, I'd go with an American ale yeast. English strains will be just as good (and generally better, if you ask me), but make for a slightly different beer.
