Personally, I prefer Pang Zhonghua, and I have practiced his handwriting since I was a child. His calligraphy is relaxed, vigorous and powerful, yet free and elegant. You won't feel tired practicing his calligraphy.
I suggest you use the temporary writing method, that is, draw a ladle instead of sticking a piece of paper on the gourd. Because the former will let you analyze the structure of words and the strength of writing, and strengthen your memory.
