I'm not that hung up on what brand I use. I go by wt and ply. I use 2 ply thread for piecing and at least 60wt or higher for my bobbin. Needle size is very important when choosing what thread you use. I bought Aurifil thread on sale and have been using it. It's 50 wt 2 ply and works great in all my machines. For quilting on a machine, weight and ply is more important then what brand. Thin will sink in the fabric, thicker thread the quilting stitches will stand out.
