I use the basic (cheapest) Stroboframe QuickFlip with that exact combination (F100 with an SB-28) that you mention. Try as I might, I can't justify selling the Stroboframe and getting something "better." Throw a Lumiquest Softbox over that SB-28 and you will be well pleased.
Most well equipped photo stores carry the Stroboframe line. Failing that, B&H sells the QuickFlip for less than $50.
As for the MB-15, I'm not the guy to ask. I am acquainted with it only from Nikon advertising literature. You will note however, that the MB-15 has a screw that attaches the battery pack to the F100. I am betting that this precludes you from using the battery pack on the Stroboframe since that same thread on the bottom of the camera body is used to attach the camera to the flash bracket. I don't know about other flash bracket manufacturers, but I'm betting that anything from Stroboframe will require you to have that thread hole free.

The MB-15 uses the thread on the bottom of the camera body but has the same thread on its body, so the only difference is that the camera will be "higher" with the MB-15. Some brackets are specifically made to work with one configuration or the other, but not both.
The MB-15 does have the srew-in mount on the bottom.
I've decided to go with either the Pro RL or the Camera flip. However I'm having a hard time finding either of these brackets. Then I got this reply from bythehour:

I can confirm that B&H and Adorama are out of stock.
I recently purchased the Newton Di100FR and use it with my Nikon F100 with the MB15 attached. I love this flash bracket. It not only does its job well but does not hinder the operation of the camera at all.
I have used it both with and without the MB15 and it works great with the larger lenses like the 17-35 f/2.8 or the 80-200 f/2.8 with the MB15 attached. Hope this helps. The website for the newton brackets is:
If you can get the Stroboframe Quick flip, it will work fine. I use it with my F100, MB15 and SB28 combination. No matter what frame you purchase, don't forget the SC-17 sync cord to connect your camera & flash. Bill
Newton brackets are certainly higher end products. I've not had the pleasure but I know several pros who swear by them.
I went with the Lindahl Bracket Plus because it was closest in design and price to the Strobo Pro-T that I originally wanted. The Lindahl is a flash-rotation design. The two main sections (top and bottom) can be broken down for packing and transport.
The main drawback with the Lindahl is that it has the flash arm on the left side of the bracket, whereas Strobo has it on the right. This design issue may be significant for F100 shooters because the left-flash placement effectively renders your MB-15 vertical grip shutter button unusable. (You have to rotate your camera clockwise to keep the flash on top of the lens.)
The Lindahl is also missing the built-in kickstand of the Strobo, which swings out to support the rig if you wish to set it down. I have an F80, MB-16, 28-105 and SB-28 set up. I have not yet had any problems standing the rig upright. However,I would suspect that using larger lenses may create a balance problem...
btw, I found that a couple of rubber washers/gaskets were required to secure the SC-17 to the flash arm with the supplied screw. Alternatively, you could add some cork.
In favour of the Lindahl is its eminently comfortable injection molded pistol grip. However, the grip is redundant for AF bodied shooters.
It seems that many photographers (myself included) are lamenting the loss of the Pro-T. Are there any Nikonians willing to syndicate an offer to buy Saunder's interest in Stroboframe??? We could buy the patents and dies and starting churning out product to meet all this pent up demand!
