well that's weird, it's normally the rope inside my lines that goes well before the tubing. What sort of hook are you using? I've speculated that the roller style hook would be kinder on lines.
I have repaired my lines in the past, using a big needle and a pair of pliers, but that was replacing the rope inside the tubing, not the other way round.
And I agree air line hose is tough, but it's usually in a tight coil. Ok if it's just a half coil at the bottom of the lines, but doesn't work if you want it the whole line length.
The semi-trailer type air hose I get is not 'coiled'.

I too have had the rope inside fail before this type of hose/tube does.

A simple solution for low cost dependable haeness lines: Rope, + Air line tube + 4x Clove Hitches.
For an 'easier on the boom grip' solution, sew up your own velcro/webbing attachment for the rope.
