The very best stuff, if you can get it reasonably, is utility conduit, 2-4"
ID. It is moderately flexible, tremendously strong (thick walls) and has a
silicone coating and a pull rope pre-installed for easy cable pulling. I
have two runs of it, and wish I had more. I've seen both electric
utilities and cable companies using it recently, and think it probably is
available as reel-ends pretty cheaply, if you ask nicely.
