I had an old aluminum walking cane (Very similar to the walking poles people use) that got screwed up, so I took the bottom section, cut off the ends then cut it in half, drilled a couple of holes, ran some 550 cord sheathing through the holes then sewed them to the ends of my tree straps.

Here is a good deal on some Aluminum Straws if you want to use them.
