We'll see on the Cuirs, still deciding about whether the slouchiness would drive me nuts. I re-homed several BVs years ago because I couldn't deal with bags without any structure.
Yay that you are considering the cuir but I totally get you with regards to the slouchiness. When I started using the small cuir without my purse organiser nor pouches, I found my things swimming around in the black hole. Not everyone likes a purse organiser though as it does take up space but just to share Samorga now makes a plain open organiser without any compartments so it might help to give some sort of structure to the cuir.
