I now have all the ingredients for a mega tree. I would like to set it up so I don't need an army of helpers to help me set/pack it up. I figure the easiest way to do this is to have some sort of pulley system to raise/lower the top ring. How do people achieve this? Do you need two pulleys to try and keep the ring basically straight so it slides up the pole better or just have a double pull from one pulley? Do you lock the top ring up there some how after raising or do you rely on the pulley rope to hold it up. Is there an other way that is better? Any thoughts/photos would be greatly appreciated. Roy.
