Have a very minor issue with the house photographer at one local venue. I clamp to the front balcony rail for open stuff, which is the sweet spot even over the pocket. She's using slightly audible gear, and pays top dollar for an annual pass in th seats right next to the rail, best place o shoot photos and video. I bought the six inch arm that ought to be enough, along with switching from 4v to 41v.
Thanks all!
