So while im debating on what colour to get my first tom bihn in I need a little help. I'm in the UK so don't want to place another order in for all the add ons. So my question is what cubes, stuff sacks etc will go great with the synapse 19. I plan to use it as an everyday bag but also as a carry on so needs to carry all my gadgets etc . Plus I liked the idea of using it as a every day when I'm on holiday to carry my camera, water bottle etc.
