I tried a number of adjustments of the mounting system but to no avail, so the Vario is going back to the shop. I've also ordered an Arkel Bug so I'll see how that goes, hoping it'll work better than the Vario so I'll be able to use it on my daily commute.

However, with the Bug mounted as far back as possible on the rack, I've found that the bag does move forward about 1cm which is enough for heel-strike to occur. I'll try wrapping some insulating tape around part of the rack to prevent the movement but the Arkel's cam-lock fixing system doesn't strike me as being as durable or as secure as the Ortlieb systems. I did try to pull the Bug off the rack but it stayed put, but after years of use I wouldn't be surprised if the spring-loaded cam-lock mechanism became weaker, but only time would tell I guess.
