JimmyH: Whenever I look at RapalloAV I have no issue with the quality of the products. The pricing, on the other hand, is *ludicrous* on the things I have looked at. A multiple of what I would pay for an essentially identical item from the likes of Jaycar or Monoprice. I don't mind paying something of a premium for local support, but not circa 300%!
Regarding what cables to run, the best option if you can manage it is to run conduit. Then you can pull through whatever cables you want and, if standards change, pull through a different one.
Yup running 25MM conduit, but that seems tight for connector heads, not sure on the legality of 32MM conduit.?
