I've got about 40 or so of those green Vipers. The ones I have lint really bad on windows or when QDing because they were bought several months ago back when there was a quality control incident with MFs. Other than that, they work great for buffing protectant and dusting the interior or for dirtier jobs like wiping your rims or drying your lower panels.
Rad21, High Noon, MFs that were bought several months ago do lint. The way I understand it, YoSteve immediately stopped selling towels when it was discovered that they were suddenly linting. I think Steve and Tim from Tacscar.com (aka Snake) worked with the manufacturer in getting the original quality MFs back and for the past couple months, their towels no longer lint. I'm not sure what the story is on the towels from CMA though.
