Excuse me, which is better, Head Head MicroGel Radical Pro tennis racket (for Murray) or YOUTEK L5 MP? It's best to talk about the feeling of playing with it.
Head Head MicroGel Radical Pro tennis racket (designed for Murray) is a more flexible, lightweight and comprehensive racket.
Utec L5 MP is heavier than wood and suitable for full-court attack.
L4 100 will be much better, unless it is professional.
