I use 4' x 16' welded wire fence panels for trellises. They are suspended on steel "T" fence posts. The top of the panel is about 7 feet above ground. I use twine for the hops to climb until they reach the wire panel. Yes, you do have to train them to grow horizontally when they reach the top of the panel, but it's easy to do. And I am out checking them every couple of days anyway.
I have read that hops do best with a certain number of leaf nodes. These develop along the bine no matter which direction they are growing. I get from 1 to 2 pounds of hops from each trellis on the established plants. Not the maximum yield but more hops than I can use in a year.
