Slackline Spider: are there any differences between the "elastic" and the normal one?
Yes, there are differences between the two.
In fact, these lines have different features for different users and needs. For example, the Pro 20 and Trick 25 have a greater elasticity and therefore require a greater body control. In other words, this kind of line is more suitable for those who have a bit of experience. On the contrary, the White 15 and Training 18 give more confidence and have a lower difficulty: that’s why they are ideal especially for beginners.
When you choose your Slackline, consider its main use.
