The main reason I don't use the PC ports is that I don't like having a cable coming out the side of the camera. I've had PC cables come loose too many times because my hand is trying to hold the camera at the same place as the PC port. It's much easier just to plug into the hot shoe base and the cable stays out of the way.
I like to use a touch of on-camera flash for fill light while firing off camera lights for my key lights. That's why I will use the above mentioned combo.
Hmm, interesting. I didn't know that this mod actually allowed input as well as output from the 3.5mm socket. This would be useful to those of us with 60d, as Canon in their wisdom took the PC sync port off.
The 580exII doesn't solve our problems either, as the PC port on that is only input, it has no output on it at all so can't be used to trigger our wireless transmitters.
How do you find the exposures? Are they fairly even throughout the room? Have you ever tried this with Canons ETTL optical sync? Do you find you need to adjust the power of the remote flashes at all? Anyone ever knocked over a stand?
