Here is a prop rig for poles I made from an old Gitzo tripod by removing one leg. Slight forward pressure on the pole against the tripod legs is enough to steady the pole if there is no wind and it feels much more secure for high shots. The legs can be folded in for carrying. I used it on New Years Eve and was able to get higher shots than before even though the crowd was very dense and the light levels were lower than usual (so much smoke). At 1/8sec @ ISO1600 @f3.5.
