Generally speaking, it is good for beginners to choose what they find more useful. I've used all your pens, but now I'm using a four-dollar pen I bought from a stall. It's been with me for two years, and it's easy to write. Plus, my writing is ok, and it's not for nothing to make it earn enough face.
Therefore, the pen is secondary. Others Wang Xizhi still uses clear water, and some calligraphers also use branches. In fact, all these show that the heart is the most important thing. If you learn well, the mental preparation for writing good words is as important as anything else.
People who yearn for calligraphy are always excellent people. I hope you stick to your dream and wish you success. If you don't understand anything, you can go to fjzhso @ 126.com to learn. I hope it will help you.
