Well...I got all kinds of stuff...

in the field..I'll use a Q-flash on a side arm.. with the diffuser cover


in my Yurt studio..I have a 2400 w/s pack and four heads sitting in the case as I am mostly using a Calumet 750 travelite behind either a ginormous softbox or a 6' Larsen Starfish on C-stand

I used to do the 3,4 light set ups..but just got really tired of lugging all that crap around..so my aesthetic sensibilities changed to meet the needs of my knees and back.. and now...even with a permanent studio..I still prefer a single light.and not even a reflector for fill. and the travelites can be dialed back to match the aperture I want to use...

If I need more light..I can just break out the full pack
