Try several and see what your machine (and you!) like. I settled in on Gutermann and Mettler's, and buy whichever one is on sale when I need it. Based on several good recommendations from this Board, I have also bought Connecting a Threads thread, but it does seem thicker and more linty to me---but the price is great and I have not had problems with it.
