Here's a picture of the Lendl hybrid pattern using my Bosworth Tour 96. I used two pieces of string. The black center strings (24.5 feet) are 17g poly strung at 51#. The outside white strings (13 feet) are 17g synthetic gut strung at 56#. This pattern required both of my machine's fixed clamps, as well as a starting clamp and a floating clamp. There was probably a more efficient way of stringing it than I did.
