I am currently using Aeronaut with the Absolute Shoulder Strap, i.e. carrying its weight with the metal snap hooks. I also have a shoulder bag packing cube, but it looks a bit too 'brutal' when used with the metal hooks.
I was wondering what would happen if I replaced the metal hooks with plastic ones coming with the Simple Shoulder Strap (which I don't have now) and try to carry the Aeronaut like that as well. The weight of mine never exceeds 20 pounds / 9kg.
So the question is: Any idea how much weight the plastic hooks could be used to carry safely, i.e. without the risk of being broken? I guess there is reason why metal hooks come with the Absolute Shoulder Strap, but I also feel they are bit of an overkill for my needs and add unnecessary weight as well. The padding of the strap however I would like to keep, that's why I only think about replacing the hooks.
