Much to my expectations, after coming back from my assignment, the bag is heavy as f&*%.
I got tired carrying it to the car!
Luckily, once I made it to the destination, I knew I'd only need the D2xs and standard zoom. Then I just put the strobes in my pockets.
But I knew this piece of equipment wasn't meant to be carried over the shoulder for long periods. It's much like carrying a 24" iMac on your shoulder.
