Another Microtex 80/12 girl here too. My machine kept shredding the thread and the LQS owner gave me a pack to try. That has become the everyday needle I use for sewing and embroidery now.
PS: Another cause of the shredding was the default setting for the foot height was changed...I don't know how or who but they live in this house. Once the dealer re-set the default all is well. LOL!
