I just got my copy of the cleaner and seen an add for .55 and . 66 cables. Do any of you use them instead of the 5/8" and the 3/4" cable ? I take it that they are to save weight, more flexile, and hold a little more in the drum. Is there any other advantage to them ? Do they hold up under power? I was just wondering why there made they don't seem to be of any other use that I can see, are they worth it ? is there something I'm missing ? I am just guessing as to why there made anyone know for sure.
