SilverCreek you did us all a big service- at least it opens up our eyes! Kudos to you!!! What better way to judge for yourself than just wrap 40 times around a hook & decide for yourself on the build up. No need for a micrometer or microscope. I like Danville's & Uni's thread and have no problem with the other brands either. Its nice to have the color assortment and variety no a days - competition is a good thing....
