I think you folks are a bit misinformed. I don't do pantos, only freehand. I work in all directions. This is the way longarms are designed. Going only right to left or left to right makes no difference. Stop & think about what your doing for a minute. When following a panto, you're going in multiple directions while following the line. The machine does it's thing of laying down thread where you say to. It doesn't care what direction you're going. The hook assembly has nothing to do with it either. All it is is an oversized sewing machine.
