A little different approach. I went to a marine canvas company and explained what I wanted (similiar to your problem). Run pipes up fence posts to desired height, about 20' apart. Attach steel cable at the top of pipe and at the top of the fence. The marine company had boat railing panel material. Mesh/small holes in canvas type material. They would put eyelets in top and bottom to run cable thru. I could take it down for winter.
