I just purchased a couple of Flex TT5's and a MiniTT1 (with an AC3 zone controller) to use with my Nikon D700 and 2 flash heads.  I have an SB800 and and SB910.  For the most part, things work as expected.  However, every 7th or 8th shot, for some reason, my exposure blows out, as if the flashes are just firing on full power, way overexposed. 
This seems to happen whether shooting TTL or manual flash. 
I'm trying to control for variables.  I'll shoot a posed subject, on a tripod, not moving the focus point so that all exposure variables remain constant: metering, aperture, shutter speed, ISO, all the same.  This problem still happens.
I believe the SB800 is the one that fires full power now and then. 
Any ideas?
My PW's are brand new and have current firmware.
Also, I unhooked the PW's and tried shooting wirelessly with the Nikon CLS infrared system and the problem didn't happen, so I'm thinking it has something to do with the signal coming from the Flex to the SB800.
I'm afraid something may be wrong with that flash head, although it's never given me any trouble and it's at least five years old.
Thanks for any help...

No real answer for you but...

-  Reset everything to factory settings then start again.
-  Make sure batteries are fresh - my pocketwizard/Nikon setup can be a bit unstable when a single battery gets low. 
-  Any possibility for radio interference?  There is one arena in town where I do get some kind of interference - I've had both the blown out shots and no-fire shots in this arena.
-  Are your flash units powering down too soon (power saving mode).  This can cause inconsistency. 
-  I never had good luck with Nikon TTL.  I know Joe McNally (is paid to) raves about this system and makes it look so easy .....  but all I get from TTL are a whole series with different exposure that should be exactly the same.
