Control rackets have a low balance and medium or soft rubber. Models such as the Adidas Cross It or the Nox ML10 are good references, depending on your level.
Who should use a control racket?
Beginners, right-side players and anyone who builds points with placement and defence. They are also kinder to the arm.
Do control rackets lack power?
They give less power on smashes than high-balance rackets, but their precision and manoeuvrability let you win points through placement.
