I'm retiring my current mega tree and going for a spiral tree this year (hopefully). Previously I used a netball goal post (with the hoop lopped off) over a star picket which worked effectively, but it's not tall enough for the revamp. I had looked at flag poles, but at 6m for what's called the "standard pole", that's too high for my liking. (Some one will go "pft, too high?"). I was thinking maybe poly pipe 4m/3.5m high and 10cm+ diameter might work - but is it strong enough? I know that a whole bunch of lights can be deceptively heavy, plus added pull of any guy wires. So what does every use? What height do you find works best for you or works best for the material the pole's made of?
