The Aurifil is the same weight but it is only 2 ply where most are 3ply. It is a very strong thread though. I started using it because I was doing CW quilts and I couldn't get those little blocks to come out the right size. My teacher checked what I was doing and my cutting and piecing was right on. She suggested changing thread and I couldn't believe how much one less ply made a difference. I also applique with it because it blends better and its great for quilting. I have connecting thread for when size isn't such a factor and I normally use a universal needle even when I made my batik quilted jacket. You can't go wrong with Aurifil. Sometimes you do have to play around with the needle size.
