From One Drop:
“Next up in the 20/20 Hindsight Series is the Burnside.
The original Burnside was released 10 years ago. Wow! It was intended as a 6061 aluminum alloy oversized competition yo-yo. For the 20/20 update, we “boosted” it. “Boosting” is taking a 6061 alloy yo-yo and re-designing for 7075 alloy. The trick is that 7075 is heavier than 6061, but the yo-yo is designed in such a way that the final weight is less than the 6061 version even though the alloy is heavier. In this case it’s 2.75 grams lighter. We also changed the look of the hub and got rid of the tap-through axle system. The profile shape remains the same.”
