I borrowed one of these from a construction buddy of mine. Worked out great and was able to fit everything in it.
Thanks for sharing Dan.
In answer to your question I don't own any lightstands nor any umbrellas (other than the stopping the rain kind in which case I take about 12 to every wedding). I don't take my monopod and the only tripod I take is a Gitzo traveller which is tiny and light which I hook onto my back pack if I need it (which is rare).
No OCF during reception Peter? Bouncing all night?
I use a photoflex dual transpac. Works awesome. Padded and it even has wheels so you can wheel it around to different sites.
This is what I have in mine right now:
2x 9.5' light stands
1 86" Parabolic
Bunch of grids
Bunch of cords
Bunch of gels
Bunch of other stuff
Nice bag Toneaero but I plan to spend ab $100 only.
