Glad to see you making progress. The hiking pole is a neat idea. I may be in touch for details some time.
I don't think attaching directly will work. If it holds most of the time, you may find it slip in the middle of the night and have to readjust in the dark. The knots might work, but they would be difficult to adjust if needed. I would suggest a bury of some type - easy to do and easily corrected when needed.
Hopefully others will have other ideas. good luck.
