I'm still going back and forth and I'm curious about something. This is from the advdepot.com website:
45L Special Kit - 86L Total Volume - Width 980MM
35L Special Kit - 66L Total Volume - Width 900MM
But how is that possible if the 45L pannier is 280mm and the 35L is 220mm wide? That would mean there is 120mm difference between the two sets, not 80mm.
And I assumed here that the "normal" 35L and 45L panniers are the same width as the "special" notched set (at least at the top).
