Voodoo, my use of these guys is usually in places where I want to create a seasonal screen and don't have much room to do it. I can sometimes employ 'green fences', an arbor/trellis with vines, but often there is not room in the budget for something like that just for a screen.
The Arrowwood may fit the bill - I'm not sure I should count on my clients providing any level of maintenance to keep something within a certain spread/size. Then again, maybe that's an opening for a future add-on service.
Mmmmm....pretty Buckthorn berries.....
