More out of curiosity than anything, but how much of your gear do you take with you for each part of a "typical" full day wedding?
We typically work in teams but are responsible for our own gear (ie. no assistants), and this is how I try to keep organized without breaking my back. Obviously it also depends on how many locations, how much walking is involved, if it is a one-stop-shop day, etc...
Bridal Prep: minimal kit in a shoulder bag (2 bodies, flash, few lenses)
Ceremony: full roller bag
Location shoot: RL Handcrafters double harness and a small shoulder bag
Reception: roller bag w/lightstands etc.. strapped to it
It'll be interesting to hear everyone else's working setup.
