in that pick i had a safety cable on my mics/extension arm. you cant really see it as it is a thin piece of cabling with a small carebiner(sp) on one end. nothing fancy, but it works perfect. i also had a shorter and lighter arm than most there. i ran the full body busmans about 1/2 way out on the arm with 2 sets of actives further out on the arm. my arm was rock solid both nights. also that night due to some issues 2 of those booms dont have mics on them as the tapers that put them up ended up running from the floor.
