For those bridge hammock users that have tried using your hiking poles as spreader bars, what kind of poles are you using?

I have some old Leki Super Makalu titanium poles that I have used and abused for the last 10 years. They still work well and I am toying with the idea of using them as spreader bars. My other thought is to hand them down to one of my boys and buy new ones.

One of the poles that looks interesting is the black diamond z-pole series. They clip together more like the aluminum spreader bars most of us use. Anyone seen or used them?

Thoughts?
