It's best to write a copy with a brush 1.0 or 0.7.

Because the pen of 1.0 is thicker than that of 0.7, and the pen of 1.0 can describe the temperament of characters more accurately and make the font more powerful and beautiful than that of 0.7, so the pen of 1.0 is better than that of 0.7.

Artistic brush is a special pen that draws thick and thin lines with the help of the inclination of the pen head. It is widely used in art drawing, hard pen calligraphy and other fields. It is a tool for artistic creation and is very practical. Fine brushwork in art has both general usage and special usage.
