Is 1/8" cable wire sufficient for muscadine vines? Some sites recommend 9 gauge wire but I have access to an adequate amount of 1/8" Thank you Michael

That should, actually, be fine. There would be no harm in, at least, trying. If it doesn't hold than you will be back to the same point. Nothing lost. I would say go for it and see if it holds.
