I may have mentioned the use of one before, but I was introduced to it by reading Dave Black's page
So generally don't use it as the only flash. Here I used a flash pointed at the ceiling to get reflected light and then increased the power on the flash with the snoot on it to get a focused, directional light.

This next shot, I increase the light that was pointed at the ceiling to minimize the contrast in the lights.

For these next shots, I kept playing with the settings of the two flashes to even them out a bit. I find that even at the same power, the snooted flash gives a higher intensity, simply because it is not diffused or reflected, it is direct, and focused by the snoot.


So, then it was time to try 3 flashes - I picked up a lightly used SB-800 a few months ago and am thrilled with it. Unfortunately they don't make them anymore. But they allow you to have an on-camera flash (I usually point it to the ceiling or wall to have reflected light) and still command the other flashes with the SB-800 (in other words, the SB-800 has commander (remote) mode and the two SB-600s I use are the slaves).
This final shot I was really happy with the balance of lighting. I have an SB-600 on a light stand behind the subject (so camera left) shot through a white umbrella at 1/16th power. I also have the on-camera SB-800 at 1/16 or 1/32 power, pointed toward the ceiling with a diffuser on it (just to bounce the light a little before it hits the ceiling)*** And finally the snooted flash is pointed directly at the faces and is also set at 1/16 power. I moved the flashed to be about 4-5 feet from the subject. Without photoshop on my work computer, I won't try a lighting diagram, but maybe I will add it later.

*** the diffuser looks like this
