Flash Triggering and also PW Flex TT5

I am trying to trigger 2 or 3 - 580EX ii flashes (or maybe even a 430?) and want to find the best solution.

All I want to do is control the flashes to flash when I hit the flash button and second would be if I could zone them and control time but again this is a second feature only and if a solution is cheap for the former, then I don't even have to have this second option for now . . I'd rather soak my money into that new 70-200 super L lens :-)

I purchased the Pocket Wizard Flex TT5 and although it came with a warning about radio noise out of the box, I'm not sure what I was experiencing was related the noise or not. Also, my understanding with the noise issue is that the flashes will flash or not flash and/or need reset or lose each other. While I did NOT experience any of these conditions I did experience some issues.

Occasionally, a picture would go into totally over exposed mode and each picture thereafter would continue to do the same until I would turn the camera (5D mk2) to M (manual) mode then it would take a picture center zone lit only and weak on the sides even though the flashes went off (obviously not very bright) then flipping back to P mode pictures would be fine, nicely lit and looking gorgeous, for about 3 to 8 pics then the same over exposed condition would occur. When flipping to M sometimes the picture would be totally unexposed and/or the flashes would not go off.

If any one can me if these experiences are Pocket Wizard Flex TT5 related I would appreciate it because I will promptly pack them up and ship them back. I also purchased the Zone controller but did not use it for this application. BTW, I did put the sleeve (AC3 I think is the name) on the flashes but it did not seem to change anything as far as I could tell AND regardless I won't run the flashes with them since all the controls are NOT accessible easily (unlike the literature states) without unhooking, unstrapping, etc. which is totally cumbersome.

Any help here will be greatly appreciated AND feel free to PM me off board for more discussion or right here as it fits. Thanks in advance.

Is it only 580s that you're having this problem with? It's not clear to me which flashes you use right now. If so, it sounds like you may be experiencing the 580 problem that's been written about a lot. Basically a weakness in the 580 that causes a failure for some units when used with HSS. The prevailing theory is that PW users are more likely to use HSS, so they see this problem more often.

There are a lot of threads on this so I won't go into details, but out of curiosity: have you been using shutter speeds over 1/200 with this setup?

T2i . 18-55 IS . 70-300 IS USM . 70-200 2.8L IS . 28mm 1.8 . 100 Macro . 430EX II . TT1/TT5 . Bogen/Manfrotto 3021 w/3265 ball-mount
