I ordered a few cones for my Longarm because the price was just too good to pass up. It is a fuzzier thread and does leave a lot of lint in the bobbin area, there are also a lot of joins in it and that worries me a bit. I know I pay a lot more for Superior, but I think I'll stick with the Sew Fine and Bottom Line. These have been my favorite for a few years now and are very dependable, there is no lint build up in the bobbin area with these.
