not all metallics or even threads are the same. floriani is great. If you are having issues when sewing you might consider turning the thread spool upside down in a cup at the back of the machine, this helps alot. Also the needle is important, there are needles that really help with this. If you think you need a certain size also get one size bigger so that the hole is a little larger in case you need it. I like Inspira needles because the hole is round and not oblong like most needles. If the metallic is on top it should be good.
