Title: Worn cross string Category: Special Creator: Jens Technical Info: Published: 2005-08-31 Description: This Babolat VF Titanium 1.30 was used as a cross string in a hybrid with Signum Pro Poly-Plasma 1.18. The outer wraps are worn off, but not at the spot where the main string was running, but obviously by friction with the ball. The main string was running "behind" the depicted cross string on the right edge of the picture.

Title: Worn cross string Category: Special Creator: Jens Technical Info: Published: 2005-08-31 Description: This Babolat VF Titanium 1.30 was used as a cross string in a hybrid with Signum Pro Poly-Plasma 1.18. The intersection area with the main string is shown. Obviously the orange color of the Poly-Plasma has been transferred to the VF Titanium due to friction. The spot marking the "native" position of the main string is not affected. The areas left and right from this intersection were exposed to the ball, and there the outer wraps are worn off.
