For starters, answers to the following questions may help:
Small or large diaphragm mics? Mics transported in a stock case, no case, or 3rd party case like a Pelican (and if a case, how big is the case)? What kind of shockmounts? Shockmounts transported in or out of the bag? Windscreens included (and if so, what size)? Mic stand attached to the bag or carried separately? What size/type of batteries? How much miscellaneous gear?
