Just got an Oneida Supercell on the mobile stand and it sucks like crazy. The "flex" hose they send with it is great, if you don't have to bend it much. Problem is, it's so stiff that it can't be rolled up into a manageable roll and it takes up too much space. I tried using a Dust Right flex hose, but it's so soft and springy that it shrinks up a lot when the SC is turned on. Has anyone had experience with a good flexible hose that doesn't shrink up?
