For those of you with the new PocketWizards, I stumbled across an interesting page on PW's website: http://www.pocketwizard.com/inspirat...hnology/range/ Long story short, it recommends that you change channels for better range against the noisy Canon flashes. They recommend channels around 345-347MHz, which they list as 2,4,5,6,20. I'm experimenting with channel 14, the highest of the bunch, and I think I like it. I was experimenting with a MiniTT1 on my camera and a FlexTT5 under my flash, in a parking garage beneath a telecom building. I had reliable range to about 110', when my back was against the wall. Anyone else experimenting?
