I have a Babylock Esante, and my dealer said not to use C&C thread. I asked why, and she said it's a bad thread. I asked what I should use, and she said, "Anything else. Doesn't matter what brand, just not C&C." She said her husband, who is the one who repairs and tunes the machines, uses C&C to test the machines. He said it's so bad, that he can tell what might be wrong by the way the thread behaves. I was kind of upset by all that. I've used C&C for many years, sewed all kinds of clothes and household items. It was always the only thread I'd ever used. I do seem to have more problems with breakage and shredding, tho. Maybe she is right. I'll have to use other brands more often and check it out.
