I have only had breakage problems with Aurifil during a class where I was trying to FMQ over some sticky water-soluble interfacing we were using to mark the quilt. We did 10 different methods and only the sticky stuff gave me breakage problems. I was missing stitches too. My needle was really gummy though, so I assumed that was the source of my woes.
I have been told to try Presencia out but I haven't bought any yet.
