Bikepacking - a viable alternative to racks & panniers

I'm interested in it but also worried my legs will rub it constantly even not full loaded, 6cm of width seems like too much in my tests on the rollers

Not actual experience but I checked out @fussballclub's I think Straight Outta Hackney and their bags seem way too wide for me. As soon as you have to move your knees outwards it's game over. That's why I went with the much smaller Deuter frame bag and top tube bag for PBP.
