Carl, like Manfred I use a Stroboframe bracket. The advantage to this bracket is that the flash is kept over the lens whether the camera is in the landscpe or the portrait mode.
However, unlike Manfred, I use a Camera Flip bracket rather than the Flash Flip model. I virtually always bounce my flash. When switching from horizontal to vertical camera positions with the Flash Flip model, the bounce flash is pointing in the wrong direction and must be reoriented.
Note: I am using the Camera Flip bracket in both of these illustrations (because I don't own a Flash Flip bracket) but, am using it in the Flash Flip mode for the above image.
Additionally, when using the Flash Flip Stroboframe, the entire unit must be rotated when switching from landscape to portrait positions.
The Camera Flip bracket keeps the flash above the camera in both vertical and horizontal positions but, the flash is always oriented correctly for bouncing in both positions. Additionally, the entire bracket doesn't need to be turned and the hand grip is always in the vertical position.
When my camera/flash is on a bracket, I like to use the top bar as a carrying handle. The above bracket has a moveable bar and I was attempting to determine how I could make it unmoveable so it would be steady as a handle. I thought of drilling and using a screw and also considered Superglue when I found this Stroboframe model on eBay for $15 USD. It was used of course!
I snapped it up and love it. I don't use a battery grip but, there might not be room to twist the camera when using such a grip.
I always use an off camera cord when shooting with a bracket. The fact that my bracket doesn't move the flash when shooting makes it easier to just wrap the cord a turn or two around the bracket to keep it out of the way.
I could use the the 7D wireless mode of flash sync but, have found that it can be problematic when shooting outdoors. Whether the wireless mode works or not depends on the brightness of the sun, the direction of the sun and the distance o my subject.
However, the sync cord approach always works.
