Interesting--I'll be curious to hear more about that method. In response to the original question, I don't know about blackberries, but for raspberries, it depends on the growing habits of the variety. Some don't need it at all. For those that do, I've read about several systems, which are integrated with decisions on pruning/mowing. I have mine on a T-trellis, with two wires spaced two feet apart, three feet off the ground. It's too little for Caroline, which I've supplemented with additional wires higher up and further out. It's about right (though may not be really needed) for Prelude. And Laurens may need more too. Polanas need nothing. I don't use clips.
