Polyamide Strings

Babolat Origin - Gauge 130 - Colour Natural  

Created from a highly innovative natural polyamide, this string offers exceptional power and comfort.
Like Natural Gut it is very responsive when strung at high tensions.
 

Kirschbaum Touch Dura - Gauge 125 - Colour Natural

Made from a combination of poly and nylon fibres, this string offers a good combination of control, durability and comfort.
It is my recommended string for juniors transitioning from a nylon or multi filament string.  It is a good stepping stone before polyester.
