I'll expound: the cotter pin fails, and then the whole thing flies apart spectacularly.

Okay, maybe not spectacularly--it just kinda dumps out the end of the tube. But at least on double-sprocket applications (like the 221 sprockets we're using), the cotter pins are more likely to hit something and fail. It's worse if you don't think about it and don't put the pins facing out each way, but the other style just avoids this problem entirely and makes things that much more idiot-resistant.

(I didn't say idiot-proof, because you know what happens then--just idiot-resistant.)
