This year I switched to a Ty-Rite bobbon for the bulk of my tying and I think it works great (able to control thread tension much better). I'm experiencing far fewer thread breaks when tying. One thing I still struggle with is having to hand re-wind thread back on the bobbin in between tying steps. The automatic bobbins (Ekich and Nor-Vise) seem like they would aid tremendously. Does anyone use either of these? How do you like them?
