I am asking what tensions others are using in a hybrid of Kevlar 16 mains and synthetic gut 16 crosses. Do you drop the Kevlar tension 5-10 % from your normal synthetic gut tension? Also, how does your set-up change with Kevlar 18 mains and synthetic gut 17 crosses? The set-up is for a friend that hits big with spin and uses a light, oversized racquet. He currently wants the tension (thick syn gut, nylon , or poly) at the max listed for the frame. Any mishit results in shearing of the string at the frame. Thanks.
