I've got the coax arms and like them fine..they keep the cables from blowing around.  Like you, I allowed the coax to pile up on the ground when I cranked down the tower, but I didn't like it.  I was afraid my dog would chew the coax or the kids would stumble over it while playing.  I didn't want to tape it to the coax standoffs either.  So, I cranked the HDX-555 tower all the way up and used an extension ladder to reach the top of the bottom section of the tower where I taped the coax to a tower leg.  I used split tubing over the coax which not only protects it, but keeps the coax from bending sharply as it comes down.  Works like a charm, and now when I crank down the tower, the coax just hangs and stays off the ground.  I also used 3/4" split tubing around the coax from where it leaves the beam and down to where it attaches to the top coax arm (with a loop for rotation} at the top of the tower.  This takes most of the pressure off the coax and prevents any sharp edges on the tower from damaging the coax as the rotator turns.
