On camera flash vs off camera flash

Here is a clear cut reason why off camera flash is more desirable for weddings. It took me literally seconds to put one flash behind the group at the other end of the tube and set the other light stand up in front of the group. With THE LIGHT CADDY you don't have to waste valuable time assembling your gear, it is already together and ready for action. With the LIGH CADDY on it's kickstand, the bag is on a 45 degree angle making it super easy and quick, not to mention STURDY- to get your gear out and back in. In this type of situation, the 45 degree angle actually was a necessity since the shark tube had a low clearance.
My assistant shot the on camera picture, I shot the off camera- what a difference a little light makes, huh?
