This is entirely user specific. It's very difficult to narrow things down to specifics and end-user functionality. We recommend some general guidelines to help you narrow down your choices. When selecting your equipment, you should always consider the following:
What is the specific role you will be filling while wearing this equipment?
What tools will you be utilizing to fulfill your role?
What items will you need the most access to, and more importantly, the quickest access to?
Do the items you select synergize well with additional gear or clothing you will be wearing?
Is the completed Battle-Belt going to be comfortable enough to wear for the length of time you anticipate wearing it?
Will the Battle-Belt be versatile, light-weight, modular and flexible throughout your planned and unplanned activities?
