I only used the expensive threads for quite a while. I was told, don't don't don't use Coats and Clark, you will see a huge difference in lint, breakage, etc..... I finally tried it due to cost. I simply could not spend as much on thread. I was shocked that one, I had less lint, and two it has only broken once. Now I must say I don't like the extra large spools because they don't work with my machine but that is not a thread issue, I think it is a machine or user error issue.
