It's just starting to show up at the FLAPS in my area, too. One of the reps brought me a sample piece of 3/16" that was coiled around a 1/2 id. I've also seen them bent onto a pretzel shape without kinking. I picked up a few pieces of it to redo some fuel lines, great stuff. If I ever redo the brake lines in mine, that's what it is going to be done with.
As far as the pvc coated lines, they should have a greenish color to them, they can be bent without worrying about the coating. They can also be bent in a much tighter radius than standard brake line. Not as tight as the copper-nickel, though. Only time I ever had issues with the coating was if I had to cut and reflare the line. The serration on the die stock for the flaring tool would dig in and mar the coating.
