In addition to the restriction that you can't go uphill, it also includes hanging chairs and T-bars. In addition, if it is really the pursuit of speed, the speed of the double board will drop faster than that of the single board. Finally, the learning curve of the double board is relatively flat. "Old women can learn, but those who learn well can't fail at one time" is my coach's original words, and veneer requires learners' physical fitness and fall resistance, and it is basically impossible to fail at all, so it is something that can be learned at a young age.
As you said, the single board has been despised by the double board for a long time, but people who hate it will hate it. You just need to have fun from it. Nothing can stop you from learning both. You'll have everything if you buy a pair of splitboard.
It is slow and dangerous to start all kinds of wrestling on a single board. However, skilled blade changing, understanding of centrifugal force, the range of action is getting bigger and bigger, but the danger is getting more and more controlled. Not only will it hardly fall, but even if the challenge falls, it will not hurt at all. The only fear is that the engraving speed is fast, and if you neglect to observe before and after, it will lead to hitting people. In short, the single board is an increasingly simple action, and the speed of the double board often exceeds the human reaction, indicating that you have been stepping on the bomb. Last year, a master of women's doubles in Chongli died of fatal speed.
Compared with the double board, the single board has the limitations of low upper speed limit and low fault tolerance rate in all areas. Of course, the advantage of single board is also obvious: the mortality rate is lower than that of double board.
