I'm more of a 'one pouch - one function' type of a guy than a 'cram everything into a bumbag' person.
Also, my days wearing military style belt order or photographer's vests are long gone and best forgotten.
Go for one of those 'tactical' waist bag things, they are only bum bags but with lots of little pockets in them
