I'm making a handlebar decision now. Very tempted to do drop bars...drops are my favorite for most applications, and the telescoping frame fit of the HaD makes it possible to size the frame for drop bars, where other cargo bikes can't do that.
The only potential pitfall may be that drops don't offer me the leverage I need to steer a heavy load. So perhaps a swept flat bar, like the Soma Clarence, or even something more cruiser-like, such as the FSA Metropolis.
Choices, choices.
