Interestingly, now that I think about it, it was the high background light that seemed to miss the most often. For the sake of mention, neither background flash had a CP-E4 to speed the recharge, and two cameras were in action for much of the night, so a variety of factors could have led the flashes to be not ready to fire.
In this scenario I would certainly hope that it was the flash's inability to fire due to recharging time rather than the Flex system failing.Under the circumstancesyou described I would expect an ST-E2 to perform fairly well.
