I wouldn't consider myself a pro but it does pay for my "habit." I recently bought a PocketWizard kit. Wow, what a difference wireless makes. I have the other light wired with flash detectors, so I'm not 100% wireless, but it has completely freed my shooting in the studio. I have a Sekonic wireless meter (that's where it all started), so I can meter often without interferring.
If you can swing it, or even if you can't, go wireless. You'll wonder why you didn't do it sooner.
On a similar note: I talked to a guy who works for a studio in the Quad cities. The owner built his own wireless setup from old garage door openers. I'm working on getting the plans for these and will post them once I do.
