I have a D2H and I have been using my SB-80DX with it, it goes to the DTTL mode and I alsu use the Quantum Turbo pack for the flash so it recycles fast. The problem I am having is the flash will rip for a couple then it won't flash for a few then pick up again, as if the battery pack wasn't there and the it was relying on the AA's in it. The quantum is working fine so it is not that, one odd thing is I can take the flash off, take the AA's cover off, out it all back on and let it rip and it is fine, flashes every time, but when I go to take game shots it seems to act up, like the camera knows I am takign photos of something I need. Is it the flash unit not working properly with the D2H, should I get an SB-800DX? I just want the flash to rip when I need it, now I know the D2H will go 8fps so maybe that is why it can't keep up.
