I am looking to update my cybersync system to something that can handle off camera TTL and recently discovered the Pocket Wizard Mini/Flex setup. I have read about some of the RF interference problems with them with the 580exII, and am wondering first off if the sock (AC5) fixes the problem.


Also, does anybody have any experience using Canon's infrared system outside in the early evening? I am wondering if I should just stick to canon's system and pick up a few more flashes instead of dropping the dough on the PW system.


Any advice would be appreciated!
