Types of string gauges –

Thinner strings pros and cons-

– Significantly more bite on the ball
– More spin
– More elasticity
– More comfort
– More feedback/response
– More lively and crisp
– Slightly more power
– Slightly more control ( due to spin and bite )
– Slightly lesser Tension stability
– Slightly lesser Playability
– Less durability
Yes , a thinner string is far superior, and the main reason why pros use thicker strings instead is only because they will burst the thinner strings too quickly due to their extremely precise ball striking. ( Balls contacts the exact same spot on the string-bed most of the time )

Most Pros uses 16 and 17 gauge strings.
For regular players like us, I recommend going as thin as you are comfortable with.
