String Facts
...all other things being equal:
HEAVIER Frame
- more power
- vibrates less
- larger sweet spot
Tension
- LOWER - more power
( if strings do not move much )
- HIGHER - more control
( for experienced players )
STIFFER Frame
- more power
- larger sweet spot
- transmits more shock
- more uniform ball response
across the entire string plane
ELASTIC String
- more power
- less shock
- more/quicker tension loss
LARGER Frame
- more power
- more resistant to twisting
- larger sweet spot
DENSITY Lower (fewer strings)
- more power
- generates more spin

SOFTER String
- vibrate less

LONGER Frame
- more velocity = more power
- more velocity = more spin
THINNER String
- more power
- more spin
Dynamic resilience of a string bed = how well it can absorb energy (pocket the ball) and return upon ball impact (snap back), thus providing the greatest control and energy return.

MORE Dynamic Resilience = More Power. The more dynamically resilient the string (or string plane), the greater the deformation and therefore the greater the energy return.
