I have a Janome Platinum 760 and a Pfaff Creative Vision. They both work just fine with any kind of thread I put in them. I do clean out the bobbin case after each bobbin. I don't have any more lint with C & C than I do with Aurifil. So far, the best is Connecting Threads. I use it most of the time, unless I need a particular color that they don't have.
