I have a lot of S-04 in the fridge and its an effort to go get US05.
I used s-04 admittedly without enough research on the strain and entirely my fault let it ferment too warm. Note: too warm for this strain is a room temperature of anything over 67, s-04 heats up and the brew will be likely fermenting several degrees over your room temp. Warmer fermentation s04 throws tons esters (some level of esters are excepted and even desired) but s04 has the potential to throw a smurf ton of esters. I felt I should warn you because my basement stays 66-68 at all times which is normally great for ales but my s04 LH milk stout smells like a banana, my incredibly supportive friends now call it the banana bread stout :-( the ester build up when I pulled the airlock and bung to rack to bottling bucket burnt my nose hairs!? Short version s-04 is great, a friend of mine through LHBC uses it all the time(it flocs well) but if you do not have temp control or a place to keep this in the LOW 60s I would stick to the s-05. The s-04 SHOULD turn out great in this beer though, it will just leave it a little "dirtier" and sweeter than the 05 (I like stouts to feel a little more full) which is why I chose to try it out instead, seeing as you already have it on hand I'm assuming you have used it before and probably know all I just told you about temps, so you will probably have a much better product then I do here haha
