"I seem to be accumulating a collection of camera bags..."
"There is no perfect camera bag, period. I have five or six myself..."
"I also am a camera bag collector."
"As another camera bag collector, I have also ammassed several bags over time..."
Geez...this sounds like the beginnings of a support group.
One I'll have to join, btw, because I, too, have a collection of bags. I do pretty much what Lowell describes...I have a couple of larger bags that holds almost all my gear, then when I go out to shoot something, I'll take only the things I anticipate needing that day and load them in a Domke bag.
