+1for almost 10 years i didn't use an organizer for my speedy30. I carry a lot of "just in case" stuff with me and even though i used various pouches to organize things, my speedy still felt like a bottomless pit.
For about a year now, i have been using samorga organizer and it made a huge difference in my enjoyment of the bag. Everything has its spot and easy access and the red of the organizer added a bit of pizzazz to my "work horse".
For those, who wonder if samorga organizer still leaves a bit of sag - it does (if you don't over stuff it). This organizer worth every penny and the looong wait for delivery.
Cheers.
