The Delta Weight is definitely something you want in your arsenal. The great thing about this weight is that you can adjust the weight from 9 to 11 grams, giving you absolute freedom and control over your freehand play. Whether your yo-yo is wide, undersized, oversized, or midsized, this is the counterweight you can rely on to hit that sweet spot of perfect weightedness. In addition to the revolutionary adjustability feature of the Delta Weight, this is the first counterweight we’ve released featuring the side groove, making the counterweight far more dynamic than anything we’ve released, and making your freehand play more carefree than ever.Manufacturer's Description of The Delta Weight
