I use Powertec and Woodcraft in the 4" size. The Powertec is cheaper but has a thinner sidewall than the Woodcraft brand, item #147880. Both brands perform well with my Laguna Pflux3 dust collector. Neither hose will collapse but both hoses will contract in length under full vacuum, that is everything unhooked except one hose. The Powertec having a thinner sidewall sags more than the Woodcraft hose when connected to a fitting parallel to the floor, see the attached pictures. The picture with two hoses is the Woodcraft and has been in place for at least two years. The picture with a single hose is Powertec and has been in position for less than six months.
Both hoses will easily coil for storage, even the much older Woodcraft hoses.
