I remember when ME conduits were added to EIO, and they were awesome. (Until I placed a dense cable conduit, then I had to bring the world back alive in MCEdit :P but that's not my point) I loved how I could just place it inside a single blockspace with all other conduits running through the base.
And now I'm wondering, why doesn't RefStorage cables exist as conduits? It looks so weird that I have to make U turns with either of the cables, it'd be much nicer if we could just add it to the bundle.
I was considering making a pull request but I lost my way in the ConduitBundle code :(
