One thread brand 6-0 is not another thread brand's 6-0. The reason the Danville Flymaster 6-0 is stronger than the Uni 6-0 is because it is thicker.
The Flymaster is 79 denier nylon and the Uni 6-0 is 135 denier nylon. Being thinner, of course the Danville is going to look more translucent because there is less material.
For breaking strength, you need to compare the Flymaster 6-0 to the Uni 8-0 which is 72 denier.
The Flymaster breaks at 11 oz and the Uni 8-0 is polyester and breaks at about 15 ounces of pressure. The difference is that polyester is stronger than nylon.
