I'm using a Crowley Tripp Naked Eye ribbon. C & T was bought by Shure a year or so ago, they continue to put out a similar product. It has Rosweillite in it, lol straight from Roswell. Very similar to my buddy's Royer 121. I've used royer copies bought from ebay & had them a/b against the 121, very decent comparison considering the huge price difference. I also had a CAD Trion for awhile, that was decent. I think the key with these chinese ribbons is the "tension", which can vary with quality control. Those Cascades have great reviews and I'd be confident that while other's have identical offerings, the qc from Cascade is what sets them apart. If I was buying a ribbon today, the fathead would be my choice.
Also be sure to check out Avantone, I don't have their ribbon, but I have a couple of their other mics and they are fantastic. Cascade, Avantone, Stellar, etc all basically come from the same plants, QC and pqackaging is the difference.
