The PWs are excellent, and they're getting better. The beta firmware brings second-curtain flash capability and some neat compensation knobs for bounced and/or high-power flash, which tells me they're trying to improve and fix whatever they can.


As far as the interference problem, I think there are two fixes that haven't gotten much publicity. One is to change channels. There's a tech bulletin on their website suggesting certain channels because they're in a frequency range (albeit tight) that seems to encounter less interference. I've started with the highest of frequencies (see the manual for the chart), and I've been having excellent results with it. Second is to use them as basic triggers, i.e. have your flash in manual mode with desired power selected. This is personal theory, and nothing that I've seen elsewhere, but they've said that the interference problem is only on the receivers with RF-noisy flashes, not on transmitters that have a local flash. Therefore, I suspect the interference problem is partially with the pre-flash (and/or recharging after the pre-flash) which manual flash would avoid. PW wouldn't want to say this, as it'd defeat the primary reason for creating these units.
