I mostly use this setup for shooting weddings. I don't have time to throw on a AC5 RF Soft Shield or an AC7 RF Hard Shield when on the job. Weddings move quickly and I need to be able to react equally as fast. Most importantly though, for me, is confidence in my gear. I NEED to know that everything is going to work. I can't be wondering if my 580EX II / FlexTT5 combo is out of range. I know that there are serveral members of this forum alone that succesfully use 580EX II's with FlexTT5's but for my own mental health, I feel more comfortable using 430EX II's. If I was using my Speedlites for pretty much anything other than weddings I probably wouldn't care.
EDIT: By the way, PocketWizard FlexTT5's come with the AC5 RF Soft Shieldand for anyone interested in my 580EX II's I'll include a AC7 RF Hard Shield. They actually make a terrific umbrella holder as they position the Speedlite close to the shaft.
