really? Watch this guy in the video is hypersynching with speedlights and doesn't use the TT5/TT1 combo. He uses a optical slave to trigger the speedlights meanwhile he can shoot at 1/8000 sec and no banding.

Ok, well the question i answered was about the PW TT5/TT1....I watched the video, and tried it myself, and i couldn't duplicate his results on a Nikon D3 and an Alien Bee 800....I have the same optical slave he's using.....at speeds from probably 1/500 up to 1/2000 the flash exposure is VERY inconsistent across the entire frame...like 3 or 4 stops from one side to the other....tried every combination of flash duration with the alien bee...it's just not good...Trying to use a speedlight was just a ton of banding.....
I have a feeling that what you're seeing in the vid, is a situation where it works with that SPECIFIC set of equipment.....it's not something that can be replicated across any system in the world of photography.....
Maybe the shutter lag on a 7D is slow enough that it happens to time correctly....
maybe his particular studio light setup has the PERFECT flash duration and t.1 and t.5 times to be able to accomplish this....
maybe the canon flashes are still putting out a pre flash when set to high speed sync in manual mode....the nikon's dont, so when they flash, they only flash once....i tried in ttl mode, and even the pre-flashes of the sb-600 in TTL mode wouldn't trigger the alien bee (or other sb-600) in time to get a good exposure...
So, i think what you're seeing is something that works, but it's like an anomaly due to a certain set of equipment working together....Just like the D70....it had a hybrid shutter that if you happened to use a PW, or an off camera flash chord, it would work up to a crazy shutter speed, b/c there was no 2nd curtain to move across the frame at those speeds, and the camera didn't think there was a flash attached...
