Fence Project: Chapter 1

Been working on the recycled-shutter portion of the privacy fence/trellis.  Coming along nicely!  Re-purposing is fun!  Blackberries? Hops? Grapes?  Blackberries are probably a bit thorny for this spot, so what is it? Hops or grapes?  What should we grow up this fence and train to the three cables that will be strung between the fence posts above the shutters? Thoughts, anybody?
