Has anyone combined a Side Effect with the larger Ristretto? I am thinking of using key straps to attach the Side Effect to the front main compartment for added organization and travel flexibility. This gives me quick access to items in the SE on-the-go, or I can securely remove the SE to access items below it at the bottom of the Ristretto. I think this makes sense because of the Ristretto's taller form factor. There may be occasions when I remove the SE altogether to get around with just the essentials.
The theory sounds good, but wondering how well this actually works out in practice.
