Like the SpinFaktor HG, the Copperhead 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.
Pictured here is a Copperhead Heavyweight that was part of a pre-production run, sold at Nationals in 2005. Sort of a market test. Several variations were made as part of the test, including a Lite version and several HG variations. Very limited numbers of these test run YoYoJams.
