After looking at the history of IGHs and reading posts here, I think one would have to really, really have issues with the shift cable to choose either the Sturmey-Archer Duomatic or SRAM Automatix two speed over a three or more speed IGH.

BTW, did you know that Shimano has a new three-speed (the SG-3R75) and a new five speed (the SG-5R35) in the works?
