The arrangement of strings (tension) of the racket
The most popular arrangement of strings is the arrangement (vertical / horizontal ratio): 18/20 and 16/19. There are also other layouts such as: 18/19, 16/18, 14/18 and others. Due to the density of the string arrangement, there are two basic arrangements: open "open" (a rare arrangement of strings, e.g. 16/19) and closed "close" (dense 18/20 string arrangement)
The string system (tension) is open
- more ball power but less control,,
- greater deformation of the impact surface,
- gives the ball more spin because the ball has more contact with the tension,
- they have a negative effect on the durability of the string (due to the easy movement of the strings in the racket, they are rubbed faster),
- lower "stiffness of the string system,
- larger "sweet spot" - clean hit field,
Closed string system
- less strength and more control,
- less deformation of the surface of the impact of the racket and thus lower dynamics of the game,
- longer string life (you need to replace it less often because it has a lower tendency to break). This is due to the fact that the "dense" string cannot move relatively freely,
- less "rotation"
- smaller "sweet spot" - clean hit field
