I have some pvc sitting in my car for just such a rig, but believe it or not, it hangs just fine by itself. I turned the metal mounting bracket around, to help counterbalance it, and taped a nice chunk of foam around the cable. so far, as long as I straighten the cord out before dropping it in, it works just fine. Was looking at my tube jig on the screen in 65 FOW the other day...good enough for me!
