Uneducated comment here, but sometimes all those odd shaped apidura bags look far more complicated than sticking on a rear rack with a pannier. Is the aero benefit really that much or is there an element of fashion going on?
Pretty sure the aero is a big deal. Especially over those kind of distances. I use a carradice style saddle bag and you do feel the drag with that compared to a saddle pack or nowt.
