Is it better to roller skate single or double?

The only way to play double-row is figure skating, which is similar to the figure skating you can see on TV

Single-row is divided into speed skating, flatland figure skating, extreme skating, etc.

Double-row skating has been popular since about 95 years ago

Single-row skating has become very popular in recent years, and it is not restricted by the venue, and it has a broader public base

So, it's better to be single-row

Single-row is better.
