Nice video, but it would have been even nicer if you had shown the inside of each bag, especially the GS sloped bag, to see how the external shape compares to the inside space available.
Just purchased a 2018 Super Tenere & I believe I would be interested in the GS Sloped Tank bag - I believe that would be the correct for my bike. I may have missed it but I see no tank bag window for maps or written notes. Did I miss it or does it not come with one.
GoPros and their accessories will fit in almost any of the bags easily. However, the larger items like the DSLR or drone would likely need one of the larger bags, especially if you are carrying a variety of lenses. Usually, people who carry these items also look to fit protection in and around these items, making each one unique, and each rider needs to figure out what works best for their needs.
