Pay attention to the weight (or Tex #) of the polyester thread for the application you want. Bottom Line, for example, is a 60wt thread that is great for piecing and quilting on most machines. Connecting Thread poly is 70wt. Glide is 40wt.
My midarm cannot handle CT; the 70wt poly shreds and breaks. Glide, which is a heavier weight, works with no problems at all in my midarm. My Bernina domestic machine does fine with 60wt poly threads. I have not tried the 70wt in it. I would probably hesitate to use 70wt for piecing because it might not be strong enough; however, I like fine thread for quilting and would try it out for quilting if I still quilted on my domestic machine.
