I rarely if ever use a staff, but if my life is going to depend on it, anything the will collapse, telescope, or was held in place by bungee cord would not be my choice.
The Folstaff is a damn solid unit once it is deployed. The bungee cord is only used to 'self assemble' and once assembled can be somewhat difficult to take apart if the joints aren't frequently
waxed. They will NOT come apart on their own.
