Seeing this thread title (again) reminded me of an interview I heard with Christine Legarde, the European Central Bank head, a while back. She was a synchronized swimmer when she was younger. She argued very persuasively that synchronized swimmers should not shave their legs so the leg hair will help keep track of where the body is located.

So, don't shave your legs for synchronized swimming. Bicyclists are split. Should a cyclist with synchronized bike lighting shave their legs or not?

(Yes, I've been out of the office far too long!)
