Hybrid
A hybrid string setup is the use of two different strings in the mains and cross strings of a tennis racquet.
This is commonly done with two completely different string materials. For example, a Multi-filament and Polyester
Hybrid setups are extremely common on the ATP and WTA pro tours right now with players choosing a strong, endurance-type string in the mains like Red Code and pairing it with a softer string in the crosses like Multifeel.
Poly-Fusion
Tecnifibre, best known for their world class multi-filament and polyester strings, have introduced a combination string designed to offer a little bit of everything...the poly fusion.
This fusion string weaves polyester and multifilament fibres together to create a unique string that offers comfort while being durable and firm at the same time.
Best used in rackets which are 280 grams and heavier, mostly used by players with experience.
