When I have to, I use a Manfrotto 681 monopod with the Manfrotto 234rc head & quick release.
The pod is about 63.5 inches high and the head adds another 2.5 inches. Only really tall Manfrotto I see is the carbon one #449 at 70.5 inches but I would not like to see its cost.
The SELF-STANDING PRO MONOPOD / Cat. No: 682B looks interesting at 67.7 inches, but I have never seen one in person
