Bronica ETR bag

I know, another bag thread, but i didn't want to step on the other thread so i figured i'd make my own, i hope that's ok.

I've been looking for a bag for my ETR gear for a while now, but it's really hard to get an idea of what a bag will hold when all i can find is pictures of how many DSLRs they fit.

I'd like a shoulder bag that can fit an ETRSi with lens, prisim, back, and grip (either with grip attached or seperate, hopefully attached) along with two other lenses (the 50, 75, and 150, with one on the body), two other backs, my Minolta Flashmeter III, the Vivitar 285HV, and a few rolls of film.

I've looked at the Lowepro Classified 250, Nova 200 and ThinkTank Urban Disguise 40, and was just wondering if anyone used one of these for a similar kit, or if something else what.

Thanks.

I have 2 for my Mamiyas: 1 Domke: 10"x10" by 18" if Y go light. And a Tamrac; 12" x12" by 18", if Y travel heavy. Both absolutely tough (have lasted 20 years) and impermeable. In the big one I can carry 2 Mamiya RB6X7 Bodies, 1 Extension tube, 5 lenses and 3 backs +Polaroid back. Each has 10 or 12 external pockecktas for film, filter, shades, etc
