I've used Mettler for 20 years and like it, but it does seem to produce lint. I'm on the verge of trying Aurifil (just ordered some) since I never have used it and I'm worried from all the info I'm reading that I'm going to like that better when I have a lot of Mettler. Maybe if that is the case I'll try Genden's idea of using Aurifil for piecing and my Mettler for applique and/or quilting.
