My S Ps don't have 'bungy cords'. Mine are LW aluminum tubes that telescope and lock in by twisting. When they are totally loose there is no resistance in going up/down ( in/out). By twisting a tube it tightens up. The lower 2 sections (on each stick) scope in/out.
To adjust simply unscrew partially and you can find the height you want and then twist the lower section to lock down.
Caution - Don't over tighten !!
It's more difficult to describe than it is actually adjust. I've heard the sticks that are bungied (sp) and they make too much noise for me.
I don't know how to accurately describe their makeup and adjustability w/o writing a book.
Suffice it to say, IF I need another set--I want them just like these.
