Many of you know that the HG material YoYoJam uses to make it's SpinFaktor HG, KOS, and Relics has increased in price so dramatically that the company has been forced to discontinue the line. But before it does you can take advantage of Erik Koslowski's new signature yo-yo the KOS Extreme. It's pretty much the same yo-yo as the KOS but with a few more grams added to is and new pogs that resemble the style used in the Spinfaktor line. We found 8 of these at the YoYoJam table at 2009 US Nats and brought them home. These are some of the last KOS Extremes left in the World so you may want to jump on this while you have the chance.
