#3. "RE: Flash bracket and battery grip" In response to Reply # 0
I used a Stroboframe Pro-T with my F4s, F5, F100w/MB-15, D2 series, and D200w/MB-D200 and it worked well. As stated above, an Anti-Twist plate is a must. If you use an SC-29 you will also need another anti-twist plate for it. The problem with the Pro-T and most other flash brackets is they are large and are very difficult to pack because they do not fold.
The best Flash Bracket I have found is the RRS Wedding Pro Flash Bracket. It is expensive and requires an L-Bracket (also not inexpensive) but it is light, extremely strong, and folds very compactly so it is easy to pack. If you use a tripod, the Arca-Swiss quick release system is the best thing since sliced bread. Good Luck and Enjoy your Nikons!
