[Avodah] amoraim and aggada

[David Riceman]

There's a clear stylistic distinction between the way Tannaim and 
Amoraim explain halacha.  Is there an equally clear distinction in 
aggada? How would you describe it?

Admittedly this is complicated since all the separate aggadic 
collections we have are from EY; in Bavel aggada was included in Talmud 
Bavli.  So ... how much of this stylistic distinction is due to geography?
