Tourna Cross Refills 10 Pack

Nice product

Works pretty well with Natural Gut strings.

Tourna Cross preventing cutting mains when hitting with spin

Once you have the appliance (or two) to insert Tourna Cross bushings in the string intersections it is silly to get more of them, when all you need is the bushings for less money.

String Preservation

I'm a professional stringer. I've used this product, or something like it, for decades. It keeps the strings from moving around, which is death to 17 or 18 gauge string, and an absolute must for gut, any gauge. Also, it adds a little tension back to the strings, which sometimes losses a little tension at tie off in the stringing process. Oh, and please, string-a-lings do not effect the trajectory, or the spin of the ball. If usage of string-a-lings were good enough for Sampras, and a number of other world class players, it should be good enough for armatures.
