I ordered the Seal-Line Smart Track rudder system and found that it doesn't come with the cable housing (it's a modular system, and you buy each component individually to fit your boat). I called the people I bought it from (Rutabaga.com) and they are out of the housing kit. Rather than wait for them to order it, then ship it to me I'm hoping to find something local that will work. Thought maybe I could save some legwork if someone has already been down this road. Has anybody used bicycle cable housing? Is there some sort of tubing I can get at the hardware store or plumbing supply house that would work? Thanks, Mark
