Having a play-around with the hubbed wands I got from Rays closing down sale
I think I can make this work with a bent coupling in the centre
Not sure what angle I'll need yet but it should add a touch more strength, not much but perhaps just enough in combination with another wand on the outside
I withdrew the Megamid pole from sale because I can use it as a reinforcing vertical pole if the weather gets really gnarly, replace the plastic cap with a small stainless eye bolt with a large diameter flexible wand section threaded thru the eye
