Ive read tha Pacific Tough Gut is pretty stiff. So: 1) Is it softer than any copoly or copolys hybrids? 2) How does it compare to copolys or copoly hybrids in control and spin production? 3) Much more durable than regular gut, such as VS? I am a baseliner who hits with topspin and drives the ball and use full copoly. Looking for a softer alternative and PTG, being gut, may be durable and should have good tension maintenance.
