You don't have to have a cavesson to lunge, especially with a horse who knows what he's doing. I have a cavesson but never use it - as you say, so heavy and jingly and dangly. It scares me, never mind a horse.
I lunge Sid (when I do, which is not often) in a well fitting headcollar. I have to swap the line over from one side to the other if I use the cheek rings, but if I use the leading ring we can change direction without a line change.
