for me, i used to carry these for my wedding shootout:-
1) Two F90X with MB10.
2) Metz flash, 45CL-4.
3) SB28 for spare.
4) Nikon 28mm-105mm macro lens.
5) Sigma 28mm-105 for spare.
6) Battery pack for Metz flash.
7) Nikon 70mm-300mm just in case.
8) Agfa Vista 200 and 400 film.
Agfa film gives a very nice red colour tones. Normally
like it very much for wedding shots.
