It is.........a pair of Performers!
Pictured above are two blue Mister Babache Performer diabolos.
Diabolo's diameter is 6 1/4 inches (160 mm).
Diabolo's height is 7 1/4 inches (185mm).
Weight 360 grams.
This diabolo looks great on stage because of its size. It is very well balanced and will indure a lot of drops even from high tosses. Catching bigger diabolos is easier because of the larger throat. The extra weight keeps it spinning longer.
The problems with this diabolo might only be if the performer cannot adjust to the added weight, especially when doing two. The extra size also makes some tricks tight where there may not be enough room for the extra-sized diabolo to fit.
