I only use Aurifil 50wt for piecing in any of the neutrals that go best with the fabrics I'm working with at the time. Very little lint, it's very fine and hardly ever breaks in my Bernina 1130. I usually buy it from afquiltsetc on Ebay for quite a bit less than my LQS sells it for, even with shipping. They also combine shipping for more than one spool. Easy, fast and dependable to buy from. I don't quilt myself, but my LAQ uses King Tut and loves it.
