With my Ristretto I always had 2 mini pouches hanging in the main compartment. A clear one containing work my work name tag and security pass and a cordura one for my earbuds. Because one was clear I could always reach in and grab the right one by feel.
Now I have my Co-Pilot I'm starting to use the pockets in the main compartment to hold a few small or mini pouches. The mesh ballistic option gives another texture to grab by feel. In the pocket with small pouches I can have any combination of cordura, clear, microsuede (FoT), cork, or mesh and I can grab the one I want without looking. In the pocket of small pouches I have cordura, clear, or clear/dyneema that I can distinguish by feel.
I can see a mini cork pouch in my future and am looking forward to the day TB start making mesh pouches in the mini size.
