@William,in the moment it is not possible to add a light kit to the Monobolos,the weight of the light kit would bring it out of balance...perhaps I will made something like that in future, but first I had to makeanother prop, I promised that on the EJC...
Last, is there a weight kit we could put if we use light kit with this kind of diabolo ?
Do any of these single sided diabolos have bearing axles?I recently got a Sundia single sider, but it has a bearing axle. I'm having trouble getting it spinning up due to confusion.
