I recently bought a reg package in which the 7-ft primary hose was apparently made of the super-flexible rubber referred to in previous posts. I hated it and switched it out for a hose of traditional flexibility. Part of the beauty of the long-hose configuration is how the hose lays nicely against the body when stowed and yet deploys smoothly and controllably. When I tried deploying that super-flexible hose it didn't want to behave. It would be an exaggeration to say it was like deploying a wet noodle--I would save that characterization for Miflex hoses--but it seemed hard to control.
