Review on NICEYRIG Shoulder Pad with Rail 🎥 Raiser: Enhance Your Camera Rig Stability and Comfort by Andrew Kamkoff

It has all the features you need including ratchet screws, multiple threaded holes and Velcro to hide the cord. You can attach a battery to it and get the right weight distribution. The bars are short but my other rigs have longer bars and I always set them to that length or less.
