Hop trellis help

[wolkphoto]

I was only able to make 15 foot trellises for my first attempt at hop growing. The magnums didn't survive but the cascades are doing well. The main vine has reached the top of the trellis as of today. Can I train it to grow back downward so I get more. The bottom is a little bushy but after 2 feet it's only one vine running to the top. I'd like to maximize yield, any help?

Can you be more specific about your trellis?

It's a 15' piece of burlap twine steaked into the ground and running up to an 18" hanging planter arm.

Tee posts, and hortinova trellis. It comes in rolls and its pretty cheap if you put lots of plants close together and run them up the trellis
