The JLS started in the summer of 1999 as an experimental run of 2000 discs. Immediately players realized that we had reached a new level in driver technology. Incredibly, the JLS flies farther and straighter than even the legendary LS. And it's got an extra measure of durability. So, it was no surprise when the JLS became the best-selling disc in most parts of the country. It is truly an amazing disc.
