Sharon, I have tested the coates sided bobbins and sideless, the neb plastic sided and the magnetic bobbins. I have not tested for # of stitches per bobbin but more for sew quality and thread breaks. I have just recently started using the plastic sided ones and they work great. I think they are my favorite. The coats sided work fine as well and I will not even try the sideless on my AMAYA's (They work fine on my EMT but still not my preference).
