I looked at that stuff, it's a bit pricy but, the spacing on the tubing is 12" I don't think you could get enough tubes in the space available. Mine are about 4" apart. That's the tightest bend radius I thought I could get by with. That's tighter than recommended but so far I have gotten by with it. Still ok after 2 winters.
