A close cousin of the SpinFaktor HG, the Copperhead was the same shape and size, and featured rim weighting like YoYoJam's composite body models, but was an all plastic model. The rim plastic was made much denser than the rest of the yo-yo by adding heavier particles to the mix. The Copperhead had even more rim weighting than the HG.
On this release, YoYojam mixed response systems. This design could be obtained with Hybrid, O-Ring, or Starburst response. Pictured here is the Copperhead with starburst response.
