I know it's not what you asked for, but my backwash line is hard plumbed underground. It's the best thing ever! As a matter of fact, after living here for 4 years, my wife (grew up with a pool) recently questioned why I don't have a blue hose like her dad used. I explained it to her and she was captivated and amazed at how awesome it was that I didn't have to roll it up all the time.
