Is it better to practice pen calligraphy straight or curved?

Beginners suggest using a straight tip, and it is not easy for beginners to practice curved tip calligraphy.

Good copybook and pen practice will get twice the result with half the effort. After two or three years, my skill in calligraphy has grown a lot. Pen can write the effect of brush writing, which is very helpful for practicing calligraphy.
