Theoretically you should not need to aerate with dry yeast. But I have done it both ways and never noticed any difference or tart flavors. And, personally, I do not like S04. And I hate WB-06.
The pro=brewer forum is a great resource for pro brewers and I have found lots and lots of information to technical questions I have. But, that being said, there are just as many bad pro brewers as there are bad homebrewers. And I have found a lot of opinions over there that I strongly disagree with. For instance, making a kolsch with the Chico strain.
