The 5 Million Dollar Home Review:
I used an separator from my 7MDH so the 18-50 (w/ hood) fits in nicely but is separated from w/e little thing I can put there. Right now it has my charger and tripod plate. The other one that came with it, the little flap that folds down just annoyed me. This was easier. It can hold anything small really: camera, remote, batteries, etc.
20D goes int he empty space, vertically, as in the shutter button is at the top. Closes how I like. Not on the velcro so I only deal with the clip.
